My notes on different ocean animals cause i really REALLY love the ocean...

Manta rays

(Manta/Mobula birostris and Manta/Mobula Alfredi)

They usually live alone or in small groups but sometimes during feedings they'll all group together and have like a huge feast.Their swimming goes sort of in a circle, kinda like how dolphins feed in a way how theyre keeping food in one place. They swim all the way to the top while eating, then swim back down to the bottom and start eating again!!! They are usually seen lining up along the sea floor and feeding there!!

We also know that the rays frequently change places while feeding. Since the ray at the front gets the most food they often switch in line! Also when theyre feeding alone theyre known to do flips in the water to stay in the one spot where all the food is.

Giant Oceanic Manta Rays(mobula birostris)can grow up to 24ft. In wingspan.

Both Manta ray species are filter feeders, eating mainly krill and plankton.

Every ray has a distinct pattern on their underside which scientists use to keep track of a certain ray for research purposes. Originally they were scientifically called Manta rays (Manta Birostris and Manta Alfredi) but after recent-ish studys it was confirmed that they are way too close to mobula rays to be separated into a different species!! So Manta rays were put into that group. The reason we originally thought Manta rays was its own species was because of the placement of its mouth. Mantas mouths are located right at the front of their bodys, while mobulas are just underneath!! The little "horns"(cephalic fins) at the front of their heads are actually used like a spoon!! They use it to scoop plankton and other small crustaceans into their mouths.They also may use it for sensory purposes and for social interactions!!

We also think that manta rays have a symbiotic relationship with remoras(sucker fish) The remoras remove ectoparasites while the rays give them better access to food and shelter!!! Manta rays are also very smart. They have one of the largest brains for an animal that isnt human and we think they have intelligence much like dolphins and elephants do!!! and believe that they can even recognize themselves in a mirror!!

Great Hammerheads (Sphyrna Mokarran)

They are the largest hammerhead shark out of all 9 species, having an average length of 4m and weight of 230kg!! They can live up to 44 years old! Its most distinguishing feature is its almost completely straight hammer-shaped head, which is called a cephalofoil, that has a prominent indent in the middle.

They can be found worldwide in costal, warm waters that are 20°C or higher. They are solitary and migrate long distances.

Great hammerheads have a faster growth rate over the other species, so they reach maturity earlier, between 5-9 years old. They give birth to live pups, around 6-42 pups once every 2 years!

Great hammerheads have long, serrated teeth, and use their head to detect pray. Their heads have electrical receptors that can sense for pray around them, even if theyre hiding in places like the sand!!

These sharks usually bottomfeed, they eat things like stingrays, cephalopods(octopus/squids), crustaceans, and other sharks!! They have been seen using their heads to pin down their pray, usually stingrays, while eating their wings! Because of their size, they arent usually prayed on by other animals!

Goblin Sharks

(Mitsukurina Owstoni)

Believed to live alone, Goblin sharks live from the surface of the water all the down to depths that reach atleast 4265ft/1300m. They only come to the surface during the night and spend most of their lives in the dark. They sense the electrical field of other fish by special organs located in their snout(rostrum). They cant fit all of their teeth in their mouth.

They havent been nearly as documented like great whites and other sharks, but its believed theyre active predators and eat fish, squids, and some crustaceans.

They reproduce with internal fertilisation/live birth. They dont actually connect their babies to a placenta and the mom likely feeds them unfertilized eggs!! Young goblin sharks know how to live on their own as soon as theyre born.

Its believed that blue sharks maybe be one of the few predators goblin sharks might have, asside from humans.

Nurse sharks

(Ginglymostoma Cirratum)

The nurse shark is a bottom feeder, eating mostly fish, shrimp, and squid, but they eat shellfish and coral too! They range from a light tan to a dark brown colour. They have two dorsal fins which are located lower on their body compared to other sharks, their tail lacks a lower lobe. They have two extentions on their mouths that are rumored to assist in detecting prey! They are pretty much harmless to humans. They can grow up to 14 ft. And live to around 25 years in captivity!!

Nurse sharks are found in warm, shallow waters of the western atlantic and eastern Pacific oceans!

They have a few predators, mostly other sharks(tiger, lemon) and humans.

Nurse sharks dont have to constantly move to breathe like other sharks, this is because they have developed a pumping mechanism(buccal pump) that pulls a current of water over their gills to keep breathing!

Sea Bunny

(Jorunna Parva)

A nudibranch that resembles a bunny, its about 1 cm long on average. Their colour varies but its usually camouflaged to the sponges they eat. The rhinophores on its head resemble bunny ears but are actually used as scent and/or taste receptors!!

Its diet consists of different sponges. They often stay by places where there is a lot of food, clinging to vegetation. They spend most of their life at the botton of tropical waters throughout the Indo-pacific ocean to central pacific. They most likely live only a few months up to a year. Theyre very toxic animals, not having many predators if any at all, but they are harmless to humans.

The Sea Anemone

(Actiniaria)

They are carnivorous invertebrates that can grow from 0.5 inches up to 6ft!! They are close relatives to coral and jellyfish, they are stinging polyps that spend most of their time attached to rocks, but they can move around! They have a foot that they can use to slowly move around, or "swim" by twisting their body around! They only really move if their environment becomes unstable.

They have tentacles that can shoot harpoon-like filaments in to their prey(which mainly consist of small fish, crabs, and plankton. But bigger species can eat jellyfish and seastars!), which then release a paralyzing neurotoxin. After their prey is paralyzed, they use their tentacles to guide it into their mouth.

There are more than 1,000 different species, most of which live in tropical waters. They can be many different colours and sizes!

They have a symbiotic relationship with green alge! Sea Anemones provide a safe place and good exposure to light, while the alge provides suger and oxygen!

Another symbiotic relationship is with clownfish. The clownfish are safe to live inside the tentacles of the anemone, and the anemone gets to eat the leftovers of the food that the clownfish eat!!

Moon Jellyfish

(Aurelia Labiata)

They are most commonly found along the west coast of north america, they can live in waters ranging ranging from -6°C to 31°C. They usually float near the surface of the water but can be found up to 3200ft. Below sea level. They usually eat zooplankton, flish eggs, crustaceans, etc.

when a moon jelly is starving it can actually keep functioning but will dramatically shrink in size!!

They have four stomachs, you can see the food through them!(which is located on the bell, or the top of the jellyfish) They have a pretty short life, usually being born in the early spring and dying early fall. They do have a thing called life cycle reversal though!! Where they grow younger instead of older!!!! They actually have no brain, heart, or anything like that. But they do have a small nervous system called the nervous net!!

Pacific Sea Nettles

(Chrysaora Fuscescens)

Sea Nettles are common in the coastal waters of California and Oregon. They are mainly a yellow or reddish-brown colour!! They live near the surface of the water column in shallow bays and harbors during the fall and winter. In sping and summer they swim in large groups in the deep ocean!! Theyre carnivores, usually eating other jellies, and zooplankton!

They cant actually see like we do, they can see light and dark using things called "eye spots" on their bell or tentacle base to get around! They usually live about 6 months, but can ultimately live up to a year!

Their stings feel very similar to a bee sting, it doesnt have any serious effects except to people who are specifically sensitive to the toxin.

Uncharismatic Fact of the Day

Stop: it's hammer time! Great hammerhead shark time, that is! Great hammerheads are the largest species in the hammerhead shark group, which contains nine species total. These sharks are also great swimmers-- so great, that they can even swim on their sides! Doing so reduces drag, and therefore the amount of energy needed to move through the water.

Daily Shark Fact - 4/16/2025

Today's shark is the great hammerhead!

The basics: the great hammerhead (Sphyrna mokarran) is the largest species of hammerhead shark, averaging around 15 feet long! These are adaptable apex predators, found in a variety of tropical ocean habitats worldwide and hunting a wide range of prey. Great hammerheads are known for swimming on their sides to reduce the drag of that big hammer-shaped head, with that huge dorsal fin maintaining lift in the water. They might spend up to 90% of their time swimming sideways!

Conservation status: critically endangered. Great hammerheads have very large dorsal fins, and have been very heavily hunted for these fins. They have slow reproductive cycles, and heavy overfishing and bycatch have significantly impacted their population numbers.

Today's fun fact: ever wonder why hammerhead sharks have heads shaped like that? The "hammer" shape to their heads, called the cephalofoil, might have evolved as a way to hunt specifically stingrays, which are a favorite food, using the wide shape to pin rays down! They will hunt by swimming low over the ocean floor, sweeping their heads from side to side to pick up on the electrical signatures of stingrays hiding buried in the substrate.

In his latest atrocity against conservation, Mark ‘the Shark’ Quartiano therealmarktheshark and equestrian.maxi ki!!ed and butchered a pregnant endangered Great Hammerhead (Sphyrna mokarran).

They posed with her body before tearing out the de@d fetuses and posing with them too.

Even though Great Hammerheads are protected in Florida state waters, Quartiano treats each offense like a parking ticket. He boasts about having ki!!ed over 10k sharks in his lifetime.

@noaa @noaafisheries need to do a better job at defending imperiled shark populations and repossess Quartiano’s fishing license. Someone needs to hold him accountable.

Facts of the Day: 🦈Great Hammerhead Shark🦈

Scientific Name: Sphyrna mokarran

Length: Up to 20 feet in length

Weight: Up to 991 lbs

Lifespan: Around 40 years old

Reproduction: They give birth to live young with their litters being between 13 to 42 pups, once every two years. 

Diet: Bony fish, crustaceans, skates, rays, other sharks, and squid

Habitat: Worldwide in coastal warm waters

Status: Endangered

Summary: Great Hammerhead Sharks are the largest of the hammerhead shark species. They also have the fastest growth rate of their species, reaching maturity between 5 and 9 years old. Unlike a lot of species of hammerheads, Great Hammerhead Sharks are solitary and don’t like to travel in schools. They will also migrate long distances, their migration routes often spanning 700 miles. Great Hammerhead Sharks often don’t eat  prey larger than stingrays but they’re efficient hunters with that prey, often using their large hammer shaped heads (called cephalofoil) to pin their prey to the sea floor making it easier to capture and eat.

A sphyrna mokarran can be nice as well.

top 5 kinds of sharks?

White shark, Carcharodon carcharias (basic answer. They are so cool. And they’re endangered/vulnerable depending on region…kinda crazy to think that The Iconic shark may not be around in 100 years :///////)

Thresher, Alopias pelagicus (specifically the pelagic one with the massive tail)

Great hammerhead, Sphyrna mokarran (goofy ass)

Lemon shark, Negaprion brevirostris (funny guy)

Bull shark, Carcharhinus leucas (freshwater baby!)

My favorite group of sharks are the requiem sharks (includes lemon sharks, bull sharks). Also it’s awesome that the great white and Greenland/mega mouth are in the same order (the mackerel sharks). Phylogeny is so neat idk.

Juvenile great hammerhead sharks rely on South Florida’s Biscayne Bay

An eight-year study highlights Biscayne Bay as a vital nursery and seasonal refuge for great hammerhead sharks, underscoring its importance across life stages and for long-term shark conservation. A new study from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science finds that juvenile great hammerhead sharks (Sphyrna mokarran), a critically endangered species,…
