Round 3 - Mammalia - Artiodactyla

(Sources - 1, 2, 3, 4)

Our final order of mammals, and second order of ungulates is Artiodactyla, commonly referred to as “even-toed ungulates”. Artiodactyla is a large and highly diverse group which includes the living families Camelidae (“camels”, “vicuñas”, “guanacos”, and kin), Suidae (“pigs”), Tayassuidae (“peccaries”), Hippopotamidae (“hippopotamuses”), Balaenidae (“right whales” and “Bowhead Whale”), Cetotheriidae (“Pygmy Right Whale”), Balaenopteridae (“rorquals”), Eschrichtiidae (“Gray Whale”), Delphinidae (“oceanic dolphins”), Monodontidae (“Beluga Whale” and “Narwhal”), Phocoenidae (“porpoises”), Kogiidae (“Pygmy and Dwarf Sperm Whales”), Physeteridae (“Sperm Whale”), Iniidae (“South American river dolphins”), Platanistidae (“south Asian river dolphins”), Pontoporiidae (“La Plata Dolphin”), Ziphiidae (“beaked whales”), Tragulidae (“chevrotains”), Antilocapridae (“Pronghorn”), Giraffidae (“giraffes” and “Okapi”), Cervidae (“deer”), Moschidae (“musk deer”), and Bovidae (“cattle”, “antelopes”, “goats”, and kin).

Artiodactyls are typically defined by the fact that they bear most of their weight equally on two or four of the five original ungulate toes. However, all living members of the infraorder Cetacea have lost their toes, replacing them with flipper-like limbs. Many artiodactyls have a relatively large head, with an elongated and narrow skull. Some families have cranial appendages, which include true horns, antlers, ossicones, or pronghorns. True horns have a bone core that is covered in a permanent sheath of keratin, and are found only in the Bovids. Antlers are bony structures that are shed and replaced each year, only found in deer. Artiodactyls have a well-developed sense of smell and sense of hearing. Similar to many other prey animals, their eyes are on the sides of the head, giving them an almost panoramic view, so that they can keep an eye out for predators while grazing. This order is highly diverse, ranging in size from the rabbit-sized Java Mouse-deer (Tragulus javanicus) to the largest mammal, and possibly the largest animal to ever exist: the Blue Whale (Balaenoptera musculus). Most are herbivorous, but many are omnivores or even carnivores.

Male artiodactyls are usually larger than females. In the majority of deer species, only the males grow antlers, and the horns of female bovines are usually smaller or absent. As this is a very diverse group, social and mating behavior vary between species. They have a tendency to form larger groups, but some live alone or in pairs. Species living in groups often have a hierarchy, both among males and females. Some species also live in harem groups, with one male, several females, and their common offspring. In other species, the females and juveniles stay together, while males are solitary or live in bachelor groups and seek out females only during mating season. Generally, artiodactyls tend to have long gestation periods, smaller litter sizes, and more highly-developed young (usually called a “calf”). Most deliver 1 or 2 calves at a time, but some pigs can deliver up to ten. Newborn artiodactyls are precocial and are born with hair and open eyes.

The oldest fossils of artiodactyls date back to the early Eocene (about 53 million years ago).

Propaganda under the cut:

More than half the species in the family Camelidae are domesticated, with the only living wild camelids being the Vicuña (Lama vicugna) (ancestor of the domestic Alpaca), the Guanaco (Lama guanicoe) (ancestor of the domestic Llama), and the Wild Bactrian Camel (Camelus ferus) (NOT the ancestor of the Domestic Bactrian).

Camelids have true canine teeth and tusk-like premolars, which are separated from the molars by a gap.

Both the Bactrian Camel (Camelus bactrianus) (image 1) and the Dromedary (Camelus dromedarius) were domesticated in ancient times for riding, transport, ploughing, and as a source of milk, meat, wool, and leather. Today, the wild ancestors of both of these species are extinct, and only feral populations of domestic camels remain. The only truly wild camel species left is the Wild Bactrian Camel (Camelus ferus), which is critically endangered.

The Wild Bactrian Camel can survive on water saltier than seawater, something which no other mammal in the world seems to be able to tolerate, including the domestic Bactrian Camel.

In Aymara mythology, Llamas (Lama glama) are sacred beings. The Heavenly Llama is said to drink water from the ocean and urinates as it rains. According to Aymara eschatology, llamas will return to the water springs and ponds where they come from at the end of time.

Babirusas (genus Babyrousa) are unique for their prominent, upwards incurving, canine tusks, which pierce out through the flesh of the snout in males. The upper canine tusks continue growing, curving backward over the front of the face and towards the forehead. If a male Babirusa does not grind his tusks (achievable through regular activity), they can eventually keep growing and, rarely, even penetrate the individual's skull.

The Domestic Pig (Sus domesticus) was domesticated from the Wild Boar (Sus scrofa) beginning in the Neolithic, and is a result of two different domestication events in both the Middle East and China. They are mostly kept for meat and leather, but are also used in medicine and as pets. The Domestic Pig is one of the few omnivorous animals to be domesticated.

The endangered Chacoan Peccary (Catagonus wagneri) is the rarest of the 3 living species of peccary, with only around 3,000 individuals left in the world. It is a “Lazarus taxon”, as its genus was first described from fossil remains of the extinct Catagonus metropolitanus. The Chacoan Peccary only lives in hot, dry, thorny areas of the Gran Chaco.

While the semi-aquatic hippopotamuses were once more diverse, only two species of different branching lineages remain: the vulnerable Common Hippopotamus (Hippopotamus amphibius) (see gif above) and the endangered Pygmy Hippopotamus (Choeropsis liberiensis).

The Egyptian goddess Tawaret is depicted as a pregnant woman with a hippopotamus head, representing fierce maternal love.

Humans have hunted whales since prehistoric times, with depictions of whaling dating back to 6000 BC. Whales are hunted for their meat, blubber, and oil. Whale oil was in high demand for lighting lamps in the 18th century. The Sperm Whale (Physeter macrocephalus) was particularly prized for spermaceti, a dense waxy substance that burns with an exceedingly bright flame that is found in the whale’s spermaceti organ. Approximately 40% of Right Whales' (genus Eubalaena) (image 3) body mass is blubber, and thus they were known as the "right" whale to kill. Today, the North Atlantic Right Whale (Eubalaena glacialis) is the most critically endangered great whale, with around 372 individuals left in the world. While whale hunting has been significantly curtailed in recent years, whales still face threats from entanglement in fishing gear, boat strikes, underwater noise pollution, plastic and heavy metals build-up, and accelerating climate change. Cetaceans are still hunted in some countries.

The Humpback Whale (Megaptera novaeangliae) is known to not only fight back against their main predators, Orcas (Orcinus orca), but also to interfere with Orca hunting parties, rescuing their prey.

The mysterious Narwhal (Monodon monoceros) is known for the long tusk of the males, which is a protruding left canine thought to function as a weapon, a tool for feeding, in attracting mates, or for sensing water salinity. Some males may grow two tusks, occurring when the right canine also protrudes through the lip. Some females may grow a tusk as well, but it is usually smaller than the tusks of males.

The critically endangered Vaquita (Phocoena sinus) is the smallest of all living cetaceans, reaching a maximum body length of 150 cm (4.9 ft) for females or 140 cm (4.6 ft) for males. The Vaquita is one of the most endangered animals in the world, with around 6-11 individuals remaining. They are endangered primarily due to bycatch in gillnets from the illegal Totoaba (Totoaba macdonaldi) fishery.

The Baiji (Lipotes vexillifer) was a river dolphin, and the last surviving member of the family Lipotidae. It is classified as "critically endangered: possibly extinct", as no specimens have been seen in the Yangtze River in over 20 years. Heavy use of the river for fishing, transportation, and hydroelectricity were the likely causes of this unique species’ extinction. While some individuals may survive, their population is likely too low to recover. If indeed extinct, the Baiji's disappearance would be the first recorded extinction of a well-studied cetacean species to be directly attributable to human influence.

The Pronghorn (Antilocapra americana) is the last surviving member of its family. While they are sometimes referred to as antelope, this is an example of convergent evolution, and their closest living relatives are the Giraffids. The Pronghorn is the fastest land mammal in the Americas, and the third fastest land mammal on Earth, with running speeds of up to 88.5 km/h (55 mph). This running speed was likely an adaptation to flee the Pleistocene American Cheetahs (genus Miracinonyx), which are now extinct.

Giraffes are the tallest living land animals, with the largest being the Masai Giraffe (Giraffa tippelskirchi). Bull Masai Giraffes can grow up to 5.5 meters (18 feet) in height, and weigh 1,300 kilograms (2,900 pounds).

Caribou (Rangifer tarandus), also known as Reindeer, are unique among Cervids in that females may have antlers, although the prevalence of antlered females varies by subspecies.

Cervid antlers are a controlled form of bone cancer. Antler growth is tightly regulated by the activity of tumor-suppressing and tumor-growth-inhibiting genes. The cancer-suppressing genes that keep growth in check also protect against cancer in general, and documented cancer rates in deer that are five times lower than rates in other mammals.

Musk Deer (genus Moschus) are not true deer belonging to the family Cervidae, but rather their family is most closely related to Bovidae. They are known for the enlarged upper canines, forming sabre-like tusks, grown by the males for display.

The family Bovidae is the largest of the artiodactyls, and ungulates in general, accounting for nearly 55% of the ungulates. They also contain the majority of domesticated animals.

The critically endangered Saola (Pseudoryx nghetinhensis) is also known as the “Asian Unicorn” due to its rarity. The first photograph of a living Saola was taken in captivity in 1993. The most recent one was taken in 2013 by a movement-triggered camera in the forest of central Vietnam.

The African Buffalo (Syncerus caffer), specifically the Syncerus caffer caffer subspecies, the Cape Buffalo, is known as one of the most dangerous animals in Africa. With nicknames like "the Black Death" or "the widowmaker", Cape Buffalos can be highly territorial and defensive, and wounded animals are reported to ambush and attack hunters. (However, Elephants, Nile Crocodiles, and Hippos are still responsible for more deaths per year than African Buffalos are. Not to mention mosquitoes and venomous snakes.)

Domestic Cattle (Bos taurus) and Zebu (Bos indicus) were both domesticated from the now extinct Aurochs (Bos primigenius) during the Neolithic revolution. While the Aurochs is now extinct, Domestic Cattle are the most successful members of their lineage, with over 1.4 billion cattle in the world.

The Springbok (Antidorcas marsupialis) is the fourth fastest land mammal, clocked at 88 km/h (55 mph). They are primarily known for their pronking behavior: bouts of repeated high leaps of up to 2m (6.7 ft) into the air. In pronking, the Springbok performs multiple leaps into the air in a stiff-legged posture, with the back bowed and the white fur on its rump raised. This behavior displays the fitness of males, both to attract mates and to ward off predators, who won’t waste time chasing a healthy, fit Springbok.

The Domestic Sheep (Ovis aries), domesticated from the Mouflon (Ovis gmelini) between 11,000 and 9000 BC in Mesopotamia, and the Domestic Goat (Capra hircus), domesticated from the Bezoar Ibex (Capra aegagrus aegagrus) around 8000 BC, were domesticated to provide easy access to meat, hides, dung (used for fuel), wool, and milk. It is thought that the birth of agriculture and domestication of livestock is what led to human civilizations, as it was hard to be nomadic with a large herd of animals. Villages popped up around pens of livestock, leading to towns, leading to cities.

Round 3 - Mammalia - Carnivora

(Sources - 1, 2, 3, 4)

Our next order of mammals is Carnivora, mammals specialized primarily in eating meat. A diverse order, Carnivora contains the living families Canidae (“dogs”), Ursidae (“bears”), Phocidae (“earless seals”), Otariidae (“eared seals”), Odobenidae (“Walrus”), Mephitidae (“skunks” and “stink badgers”), Ailuridae (“Red Panda”), Procyonidae (“raccoons”, “coatis”, “ringtails”, “kinkajous”, and kin), Mustelidae (“weasels”, “badgers”, “otters”, “Wolverine”, and kin), Nandiniidae (“African Palm Civet”), Viverridae (“civets”, “genets”, “Binturong”, and kin), Herpestidae (“mongooses”), Eupleridae (“Malagasy mongooses”), Hyaenidae (“hyenas”), Prionodontidae (“Asiatic linsangs”), and Felidae (“cats”).

As the sixth largest order of mammals, Carnivora is very diverse and exhibits a wide array of body plans, varying greatly in size and shape. They usually have large, conical, thick, stress-resistant canine teeth. Most species have eyes on the front of their face, pointing forward. They often have a very well-developed sense of smell. Some carnivorans have retractile or semi-retractile claws. Carnivora is separated into two suborders, Caniformia and Feliformia, with Caniforms containing canids and their relatives and Feliforms containing felids and their relatives. (Yes, even in taxonomy, there is a dichotomy between cats and dogs.) Caniforms have longer jaws and more teeth, with less specialized carnassial teeth. They also tend more towards omnivory and opportunistic feeding, while the feliforms, other than the viverrids, are more specialized for eating meat. Some carnivorans have secondarily evolved mainly herbivorous diets. They exist in almost every habitat, from the polar North to hyper-arid deserts to marine seas.

Male carnivorans are usually larger than females. Some species are social while others are solitary. Some species only meet to mate, some form family groups organized around a breeding pair, and some involve a single male or males leading a harem of females and their young. Carnivores usually invest a lot into their young, teaching and raising them to adulthood.

Carnivoramorpha as a whole first appeared in the Paleocene of North America about 60 million years ago, as small marten-like or civet-like predators of insects, lizards, and other small vertebrates. Feliforms and Caniforms split around the Middle Eocene, about 42 million years ago. The precursors to the living feliforms remained forest-dwelling, arboreal or semi-arboreal ambush hunters, while the caniform precursors were more mobile, opportunistic hunters.

Propaganda under the cut:

Canids tend to live as monogamous pairs. Wolves (Canis lupus), Coyotes (Canis latrans), African Wild Dogs (Lycaon pictus), and Dholes (Cuon alpinus) live in groups that include a breeding pair and their offspring. Wolves may even live in extended family groups. Living in family groups allows these animals to work together to take down prey larger than themselves.

The Domestic Dog (Canis familiaris) was the first species to be domesticated by humans, from the Wolf (Canis lupus), more than 30,000 ago when humans were still hunter-gatherers. Domestic Dogs have evolved alongside humans, adapting to better understand and communicate with us, read human body language and expressions, and smell human emotions. Both dogs and humans release oxytocin while spending quality time together, a sign of a strong social bond. Over 340 breeds of Domestic Dog have been selectively bred for tasks such as hunting, herding, pulling loads, detecting a variety of scents, protection, and companionship, with various breeds also filling roles in therapy, aiding disabled people, and assisting police and the military.

According to the Creation Myths of the Serer People, jackals were the first animals on Earth, and the first intelligent beings before humans, and will be the last. In some stories, the jackal is sent to Earth by Roog as a messenger, and in others as a fallen prophet for disobeying the laws of the divine. The movements of the jackal are carefully observed, because the animal is viewed as a seer who came from the transcendence and maintains links with it. Although believed to be rejected by the other animals and deprived of its original intelligence, it is still respected because it dared to resist the supreme being who still keeps it alive.

The Polar Bear (Ursus maritimus) is the largest land carnivore, with adult males weighing 300–800 kg (660–1,760 lb) and being 200–250 cm (6.6–8.2 ft) long. Females are smaller at 180–200 cm (5.9–6.6 ft) with a weight of 150–300 kg (330–660 lb). Adults may stand 130–160 cm (4.3–5.2 ft) tall at the shoulder. The largest Polar Bear on record, reportedly weighing 1,002 kg (2,209 lb), was a male shot at Kotzebue Sound in northwestern Alaska in 1960.

The word “panda” derives from the Nepali word “ponya”, which means “ball of the foot” and “claws”. The Nepali word for the endangered Red Panda (Ailurus fulgens) is "nigalya ponya", which has been translated as "bamboo-footed", due to the animal’s adapted wrist bone which allows it to grip bamboo. When the Red Panda was first described in 1825, it was named an English shortening of this name: “panda.” For more than 40 years the Red Panda was known as simply the panda: the one and only panda. However, when the vulnerable Giant Panda (Ailuropoda melanoleuca) was described in 1869, it was also given the name panda. Historically, there was much debate over the taxonomic positions of these two species, as they were both carnivorans that had adapted to a very specific diet of mostly bamboo. However, we know today that the Giant Panda is indeed a bear and not closely related to the Red Panda, which is the only living member of its own family.

The endangered Giant Otter (Pteronura brasiliensis) is a semi-aquatic predator of north-central South America, and is capable of bringing down animals as tough as a small caiman. Giant Otters live in extended family groups, and are highly social with each other, but extremely territorial of other groups. Battles between groups sometimes break out at the boundaries between territories.

Weasels (genus Mustela) have a behavior called the “weasel war dance”, which consists of a frenzied series of hops sideways and backwards, often accompanied by an arched back and a frizzed-out tail. The weasel war dance happens when the animal is excited or happy, and often occurs after they have caught or killed their prey, or are playing.

Ferrets (Mustela furo) were domesticated from the European Polecat (Mustela putorius) around 2,500 years ago. The Romans used ferrets to hunt rabbits, rodents, and moles, as they are specifically adapted to squeeze into holes after prey. Genghis Khan, ruler of the Mongol Empire, is recorded as using an army of ferrets in a gigantic hunt in 1221 that aimed to purge an entire region of wild animals.

The smallest carnivoran is the Least Weasel (Mustela nivalis). Average body length (not counting the tail) in males is 130 to 260 mm (5 to 10.2 in), while females average 114 to 204 mm (4.5 to 8 in). Males weigh 36 to 250 g (1.3 to 8.8 oz), while females weigh 29 to 117 g (1 to 4.1 oz). Despite their diminutive size, Least Weasels are still effective predators, and can take on prey up to the size of a rabbit.

The North American Black-footed Ferret (Mustela nigripes) declined throughout the 20th century, primarily as a result of declines of its main prey, Prairie Dogs (genus Cynomys). In 1979, it was declared extinct. However, a small wild population was discovered in Meeteetse, Wyoming in 1981! A captive breeding program was launched, using these ferrets, and a reintroduction campaign was put into play. Today, over 200 mature individuals are in the wild across 18 populations, with four self-sustaining populations in South Dakota, Arizona, and Wyoming. In 2008, the Black-footed Ferret’s IUCN status was changed from “extinct in the wild” to “endangered”. In February 2021, the first successful clone of a Black-footed Ferret, a female named Elizabeth Ann, was introduced to the public. She was cloned using frozen cells from Willa, a female Black-footed Ferret who died in the 1980s and had no living descendants. This exciting development opened the doors to a new option for introducing much-needed genetic diversity into the captive breeding population. Elizabeth Ann could not breed herself, due to a condition unrelated to the cloning process, but in 2024, two new Black-Footed Ferret clones, Noreen and Antonia, were also cloned from Willa’s frozen cells. Antonia has since birthed a male and female kit, and Noreen is waiting for a suitable match.

The Honey Badger (Mellivora capensis) is famous for its strength, ferocity, and toughness. It is known for being able to fearlessly fight back when cornered, sometimes even dissuading Lions (Panthera leo) and Spotted Hyenas (Crocuta crocuta) from attacking it. It often raids beehives in search of honey and larvae, and is unbothered by bee stings, which have trouble penetrating its thick skin. They have been observed to kill and eat Black Mambas (Dendroaspis polylepis). They are also highly intelligent, and have been observed manipulating tools and performing complex problem-solving. Despite all this, they are only dangerous to humans if provoked, and most of their reputation comes from their willingness to defend themselves.

There are three species of raccoon, and the small, critically endangered Cozumel Raccoon (Procyon pygmaeus) is the rarest of them. It is native only to Cozumel Island off the coast of the Yucatan Peninsula, Mexico. It is estimated there are only around 192 mature individuals left in the world.

Walruses (Odobenus rosmarus) have powerful, mobile lips that they can use to generate high-powered suction. They do this to feed on one of their favorite prey items: clams. A Walrus can suck the meat out of a clam by sealing its powerful lips to the animal’s shell and withdrawing its piston-like tongue rapidly into its mouth, creating a vacuum. They can also use their mobile lips to whistle in the same way humans do!

The Baikal Seal (Pusa sibirica) is the only species of exclusively freshwater seal. They are native only to Lake Baikal in Siberia, Russia. The most recognizable characteristic of the Baikal Seal is its large, dark eyes. Lake Baikal is the deepest lake in the world, and has varying levels of light intensity. The seal’s large eyes allow it to take in as much light as possible in this environment.

The African Palm Civet (Nandinia binotata) is the most genetically isolated Carnivoran, being the only species within its whole superfamily.

The Jaguar (Panthera onca) employs an unusual killing method: it bites directly through the skull of mammalian prey, between the ears, to deliver a fatal blow to the brain. It does this with a powerful bite force of 1,500 PSI. This bite also allows it to pierce the shells of turtles and the osteoderms of caimans.

When Cecil the male African Lion (Panthera leo leo) was killed in July 2015 by Walter Palmer, an American recreational big-game trophy hunter, there was international uproar and a change in the atmosphere regarding trophy hunting. There was also worry amongst the scientists who had been studying Cecil’s pride that his cubs were now in danger. When one or more new male Lions replace a previous male(s) associated with a pride, they often kill any existing young cubs, to ensure that only their bloodline is produced going forward. However, Cecil had formed a partnership with another male lion named Jericho. When Cecil was killed, Jericho took over the pride but did not kill Cecil’s cubs, and also protected them from any rivals.

The Domestic Cat (Felis catus) was domesticated from the African Wildcat (Felis lybica) about 10,000 years ago. Ancient Egyptians revered the Domestic Cat, and families would take their dead cats to the sacred city of Bubastis, where they were embalmed and buried in sacred repositories. Cats eventually replaced Ferrets as the pest-controlling housepet of choice in Ancient Greece and Rome, as they were considered more pleasant to keep around the house. Like dogs, they have adapted to live alongside us, evolving new vocalizations, body language, and behaviors specifically for communicating with humans, and generally becoming a social species (the African Wildcat is typically solitary and territorial). Today, there are over 41 breeds of Domestic Cat, and they are kept mainly for companionship and pest control. Unfortunately, they have also become one of the most abandoned pets.

The Cheetah (Acinonyx jubatus) is regarded as the fastest-running land animal. It is capable of running at 93 to 104 km/h (58 to 65 mph) in a sprint.

The Asian Palm Civet (Paradoxurus hermaphroditus) is threatened by poaching and the illegal wildlife trade in Indonesia. They are captured for use in the production of kopi luwak. Kopi luwak, also known as civet coffee, is a coffee that consists of partially digested coffee cherries, which have been eaten and defecated by the Asian Palm Civet. The cherries are fermented as they pass through a civet's intestines, and after being defecated with other fecal matter, they are collected. What was once a traditional drink, made from coffee cherries collected from civet feces in the wild, has become increasingly commercialized due to international demand and curiosity. Now, to meet demand, Asian Palm Civets are captured, kept in battery cages, and forcefed nothing but coffee cherries. The civets in kopi luwak farms are kept in abysmal conditions which include isolation, poor diet, small cages, and a high mortality rate. Kopi luwak is one of the most expensive coffees in the world, with retail prices reaching US$100 per kilogram (2.2 lbs) for farmed beans and US$1,300 per kilogram for wild-collected beans.

In some countries, the African Civet (Civettictis civetta) (image 4) is threatened by capture for the perfume industry, as its pheromone civetone is often used as a natural musk. The Calvin Klein-brand male cologne Obsession utilizes synthetic civetone, making the cologne highly attractive to feliforms. Obsession is sometimes used in the field to attract wild cats to camera traps, and is also used in zoos and sanctuaries as scent enrichment.

Mongooses (family Herpestidae) are one of at least four known mammalian taxa with mutations in the nicotinic acetylcholine receptor that protect against snake venom. This makes them fierce and effective predators of venomous snakes.

The Spotted Hyena (Crocuta crocuta) lives in large clans which can consist of up to 80 individuals. These clans are typically led by females, though they can occasionally co-dominate with a male. Clans are run by a matriarch, and her youngest female cub will become the new matriarch when she passes. When a male co-dominates with a female or is otherwise able to lead, this is because the male was born to the matriarch of the clan and has taken the rank directly below his mother.

The Aardwolf (Proteles cristatus) is a small, basal hyena that mainly eats termites. Like other animals adapted for eating termites, it has a long, sticky tongue.

Carnivorans usually occupy a very important part of the ecosystem, and most apex predators are carnivorans. Apex predators can be considered ecosystem engineers, due to the huge impact they have on their environment. One of the most famous examples of this was the reintroduction of Wolves (Canis lupus) in Yellowstone National Park. In 1884, the state of Montana instituted a bounty on Wolves: one dollar per Wolf killed. Wolves were considered a “menace” to Yellowstone’s wildlife, and more concerted efforts mounted to exterminate them. The Elk (Cervus canadensis) population began to explode, and they grazed their way across the landscape, killing young brush and trees. As early as the 1930s, scientists were alarmed by the degradation and were worried about erosion and plants dying off. By the 1970s, there were no resident populations of Wolves in Yellowstone, and Wolves had been almost completely eradicated in the lower 48 states. In 1974, the Wolf was listed in the endangered species act.

Starting in January 1995, Wolves from Canada began to be relocated to Yellowstone National Park. In the years that followed, wolves brought the Elk population down and their presence protected the open valleys from overgrazing, as the fear of predators kept the herds on the move. Willows (genus Salix) began to grow larger, with an increase in size of 1,500% by 2020. With the foliage returning to the park, Beavers (Castor canadensis), Lynxes (Felis lynx canadensis), Wolverines (Gulo gulo) (image 1), and many other formerly reduced species began to rebound. Beaver colonies have grown from 1 in 1995 to 19 by 2015 with four active dams in use. The dams build wetland ecosystems, used by millions of other species. This is an enduring example of a Trophic Cascade: a powerful indirect interaction that can control entire ecosystems, occurring when a trophic level in a food web is removed or added.

Even though domestic carnivorans like the Domestic Dog, Domestic Cat, and to a lesser extent, the Ferret, are some of the most popular pets in the world, most wild carnivorans have been, and still are, unfairly demonized. Many species have been overhunted, resulting in extirpation in some areas. Even early “conservationists” did not understand the value of predators, considering it a boon to the ecosystem to wipe them out entirely. Bounties are still placed on carnivorans today, and many ranchers and farmers push to have them completely wiped out to protect their livestock. If you cross the border of Yellowstone into a nearby town, you must be ready to hear all about how Wolves are evil creatures who kill for pleasure, and are going to kill all the precious Elk. It is a constant uphill battle to reintroduce carnivorans who may have been extirpated from their historical ranges. Yet in some places, humans have learned to coexist with these important parts of the ecosystem. One of the best ways to support carnivorans is through ecotourism. Locals tend to see more value in the predators they have to share space with when visitors are both excited about and bringing in tourism revenue because of these animals.

Round 3 - Mammalia - Chiroptera

(Sources - 1, 2, 3, 4)

Our next order of mammals is Chiroptera, commonly called “bats.” Chiroptera is the second largest order of mammals after Rodentia. Bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. They are divided into the families Pteropodidae (“megabats”), Rhinopomatidae (“mouse-tailed bats”), Craseonycteridae (“Kitti's Hog-nosed Bat”), Megadermatidae (“false vampire bats”), Rhinonycteridae (“trident bats”), Hipposideridae (“Old World leaf-nosed bats”), Rhinolophidae (“horseshoe bats”), Nycteridae (“slit-faced bats”), Emballonuridae (“sac-winged bats” and “sheath-tailed bats”), Myzopodidae (“sucker-footed bats”), Mystacinidae (“New Zealand short-tailed bats”), Thyropteridae (“disk-winged bats”), Furipteridae (“Smoky Bat” and “Thumbless Bat”), Noctilionidae (“bulldog bats”), Mormoopidae (“ghost-faced bats”, “mustached bats”, and “naked-backed bats”), Phyllostomidae (“New World leaf-nosed bats”), Natalidae (“funnel-eared bats”), Molossidae (“free-tailed bats”), Miniopteridae (“long-fingered” and “bent-winged bats”), Cistugidae (“wing-gland bats”), and Vespertilionidae (“vesper bats”).

Bats are the only mammals capable of true and sustained flight, with their forelimbs adapted as wings. Their wings are a patagium of skin stretched between 4 fingers, with their thumbs pointing forward and supporting the leading edge of the wing. The wings of bats are much thinner and consist of more bones than the wings of birds, allowing bats to maneuver more accurately and fly with more lift and less drag. The surface of the wings is equipped with touch-sensitive receptors on small bumps called Merkel cells, also found on human fingertips. In bats, each of these bumps has a tiny hair in the center, making it even more sensitive and allowing the bat to detect and adapt to changing airflow. While bats are highly agile in the air, they can only crawl or drag themselves awkwardly across the ground, and most of their time not in the air is spent roosting upside down. However, a few species, such as the New Zealand Lesser Short-tailed Bat (Mystacina tuberculata) and the Common Vampire Bat (Desmodus rotundus) are able to walk or even run on all fours. Most bats are insectivores, and most of the rest are frugivores (fruit-eaters) or nectarivores (nectar-eaters). A few feed on vertebrates, such as the specialized blood-drinking vampire bats (subfamily Desmodontinae), the bird-hunting Greater Noctule Bat (Nyctalus lasiopterus), the fish-catching Greater Bulldog Bat (Noctilio leporinus), the frog-eating Fringe-lipped Bat (Trachops cirrhosus), and the Spectral Bat (Vampyrum spectrum) and Ghost Bat (Macroderma gigas) which sometimes feed on other bats. Carnivorous bats make use of echolocation for navigation and finding prey, while herbivorous bats use their more well-developed eyesight. Apart from the Arctic, the Antarctic and a few isolated oceanic islands, bats exist in almost every habitat on Earth.

Some bats lead solitary lives, while others live in colonies of millions. In some, the females live in groups while the males are solitary, or males and females will live in separate groups. Most species are polygynous, where males mate with multiple females. Some species are promiscuous, where both sexes mate with multiple partners. A few species form monogamous pairs. Female bats use a variety of strategies to control the timing of pregnancy and the birth of young, to make delivery coincide with maximum food ability and other ecological conditions. In most bat species, females carry and give birth to a single pup per litter. The young emerges rear-first, possibly to prevent the wings from getting tangled, and the female cradles it in her wing and tail membranes. In social species, females give birth and raise their young in maternity colonies and may assist each other in birthing. A few species also assist in suckling other mothers’ young. Most of the care for a bat pup comes from the mother, but in monogamous species, the father will also play a role in childcare.

The fragile skeletons of bats do not fossilize well, but Chiroptera is assumed to have arisen in the Eocene. The oldest known bat fossils include Archaeonycteris praecursor and Altaynycteris aurora (55–56 million years ago), both known only from isolated teeth. The oldest complete bat skeleton is Icaronycteris gunnelli (52 million years ago).

Propaganda under the cut:

The eyes of most carnivorous bat species are small and poorly developed, leading to poor visual acuity, but no species is truly blind. Microbats may use their vision for orientation and while travelling between their roosting grounds and feeding grounds, as echolocation is effective only over short distances. Some species can even detect ultraviolet (UV) light.

The smallest mammal in the world is the Kitti's Hog-nosed Bat (Craseonycteris thonglongyai), also known as the Bumblebee Bat (though the the Etruscan Shrew [Suncus etruscus] is smaller by body mass). An adult Kitti's Hog-nosed Bat is about 29 to 33 mm (1.1 to 1.3 in) in length and weighs around 2 g (0.071 oz).

On the other wing, the largest bat in the world is the Giant Golden-crowned Flying Fox (Acerodon jubatus) which can reach a weight of 1.6 kg (3.5 lb) and has a wingspan of 1.7 m (5 ft 7 in).

Bat dung is mined as guano from caves and used as a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Bat guano also contains fine particles of insect exoskeleton, which are largely composed of chitin. Chitin from insect exoskeletons is an essential compound needed by beneficial soil fungi, as chitin is a major component of fungal cell wall membranes. This fungi then improves soil fertility. However, unsustainable harvesting of bat guano may cause bats to abandon their roost. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, fungi, invertebrates, and vertebrates in the cave. The loss of bats from a cave can result in the extinction of species that rely on their guano.

The extinct bats Palaeochiropteryx tupaiodon and Hassianycteris kumari, both of which lived 48 million years ago, are the first fossil mammals whose colorations have been discovered. Both were reddish-brown.

The fastest flying bat, the Mexican Free-tailed Bat (Tadarida brasiliensis), can achieve a ground speed of 160 km/h (100 mph)!

Mexican Free-tailed Bats are one of the few species to "sing" like birds. Males sing to attract females.

Greater Bulldog Bats (Noctilio leporinus) “honk” to warn each other when they may be about to collide.

Carnivorous bats make use of magnetoreception, in that they have a high sensitivity to the Earth's magnetic field, like birds. These bats use a polarity-based compass, meaning that they differentiate North from South, unlike birds, which use the strength of the magnetic field to differentiate latitudes.

Scientists reported in January 2025 that they had discovered how some bats travel hundreds of miles in the spring to give birth in warmer temperatures: they surf storm fronts.

The Spotted Bat (Euderma maculatum) can travel as much as 38.5 km (24 mi) in one night in search of food.

Many species of plants depend on bats for seed dispersal. The Jamaican Fruit Bat (Artibeus jamaicensis) has been recorded carrying fruits weighing 3–14 g or even as much as 50 g.

Nectar-eating bats have acquired specialised adaptations. These bats possess long muzzles and long, extensible tongues covered in fine bristles that aid them in feeding on particular flowers and plants. These long, narrow tongues can reach deep into the long cup shape of some flowers. When the tongue retracts, it coils up inside the rib cage. The Tube-lipped Nectar Bat (Anoura fistulata) has the longest tongue of any mammal relative to its body size.

Around 500 species of flowering plant rely on bat pollination. Because of this, some of these flowers have adapted to only open their flowers at night.

Due to the specialized metabolism of Vampire Bats (subfamily Desmodontinae) they are highly susceptible to starvation if they fail to feed within 70 hours. To combat this, vampire bats engage in reciprocal altruism, and will feed each other by regurgitating blood. If a bat cannot find food two nights in a row, due to injury, illness, or simple unluckiness, one of its colony mates may feed it. Vampire bats who are more “popular” in the colony may be fed more often.

White-nose syndrome (WNS) is a fungal disease in North American bats which has resulted in the dramatic decrease of the bat population in the United States and Canada, killing millions and causing a 90% decline in some areas. The condition is named for a distinctive fungal growth of Pseudogymnoascus destructans around the muzzles and on the wings of hibernating bats. It is likely the fungus was brought to North America from Europe by cavers who didn’t wash their equipment. Bats in Europe seem to be resistant to the fungus. The Forest Service estimated in 2008 that the die-off from white-nose syndrome means that at least 2.4 million pounds (1.1 million kg or 1,100 tons) of insects will go uneaten, possibly leading to crop damage or having other economic impact.

It has been estimated that bats save the agricultural industry of the United States anywhere from $3.7 billion to $53 billion per year in pesticides and damage to crops. This also prevents the overuse of pesticides, which can pollute the surrounding environment, and may lead to resistance in future generations of insects.

Homosexual relations have been observed in the Bonin Flying Fox (Pteropus pselaphon) and the Indian Flying Fox (Pteropus medius).

The Christmas Island Pipistrelle (Pipistrellus murrayi) was declared extinct in 2009. This extinction was likely caused by introduced, invasive species such as Domestic Cats (Felis catus), Black Rats (Rattus rattus), Common Wolf Snakes (Lycodon capucinus), and Yellow Crazy Ants (Anoplolepis gracilipes). The bats could have also been poisoned by the insecticide Fipronil, used to control Yellow Crazy Ant Colonies.

In China, bats have been associated with happiness, joy, and good fortune. Five bats are used to symbolise the "Five Blessings": longevity, wealth, health, love of virtue, and peaceful death.

A new threat to bats has arisen in the form of bat taxidermy. Bat taxidermy, where bats are either mounted in glass, encased in resin, articulated as a skeleton, or simply stuffed, is growing in popularity as “quirky” decor. However, many sellers will claim to be ethical when they are not, and are actually catching and killing bats to meet the rising demand of this new market. In some cases, entire caves will be gassed so that the bat carcasses can be harvested by the thousands. Many of the bat species used for oddity decor are declining or even endangered. The transport of bat carcasses overseas has also been linked to the spread of disease.
