Bradypus tridactylus | Joseph Wolf (1820-1899)

[mammalidentifier]

all kidns of strange and wonderful beafts in the world. how do we even know them all. wh

That’s the beauty of it: we don’t know them all! We’re constantly discovering new species! Granted, some of these discoveries weren’t completely unknown to science and were only misidentified as a different animal, but they’re still pretty cool nonetheless. Here are some mammals that were discovered in the past few years:

The Popa langur (Trachypithecus popa), first described in 2020.

The northern greater glider (Petauroides minor) and the central greater glider (Petauroides armillatus), upgraded from subspecies of the southern greater glider (Petauroides volans), to their own species in 2020.

The Ramari’s beaked whale (Mesoplodon eueu), described from a single beached specimen in 2021!

The striking Halloween colored Nimba myotis bat (Myotis nimbaensis), described in 2021.

The southern maned sloth (Bradypus crinitus), first described in 2022.

The Benin tree hyrax (Dendrohyrax interfluvialis), first described in 2022.

The eastern Mindanao gymnure (Podogymnura intermedia) and the Kitanglad gymnure (podogymnura minima), first described this year, in January 2023.

And the Talpa hakkariensis mole, described just last month in August 2023!

This 16th-century artwork is of a 'haut', which are said to live in the trees. It has been identified with species of three-toed sloths such as Bradypus variegatus which are found in the forests of Central and South America. This artwork comes from 'Cosmographie universelle' (1575) by the French explorer and writer Andre Thevet (1516-1590). The book describes the history and geography of the lands in which Thevet had travelled. The two volumes contain over 1000 pages divided into 23 books. This woodcut is from chapter XIII of book XXI.

Phoretic (living on the surface, but not parasites) organisms on sloths

A sloth moth is a coprophagous moth which has evolved to exclusively inhabit the fur of sloths and to use sloth dung as a substrate for the early stages of reproduction. Sloth moths include Bradypodicola hahneli,[1] Cryptoses choloepi,[1] Cryptoses waagei,[2] Cryptoses rufipictus,[2] and Bradypophila garbei.[2]

Certain lepidopteran moths of the snout moth family Pyralidae (namely subfamily Chrysauginae) have evolved to inhabit sloth fur exclusively. Typically, sloth moths follow a life-style broadly on the lines of Cryptoses choloepi, a moth in the snout moth family that lives exclusively in the fur of the brown three-toed sloth Bradypus variegatus infuscatus. Adult female moths leave the fur of the sloth to lay eggs in the sloth droppings when the sloth descends, once a week, to the forest floor to defecate. The larvae of Cryptoses choloepi live in the dung and newly emerged moths later fly from the dung pile into the forest canopy to find a host sloth.[3][4]

Chrysaugine moths, such as Cryptoses spp., spend their lives as adults in the fur of sloths, particularly the three-toed species, except when the sloths descend to defecate and females fly to the sloth dung to oviposit. An imbalance in population sex ratios favouring males has been noticed and surmised as female moths not making it back to host sloths after ovipositing.[1]Pale-throated sloth (Bradypus tridactylus)

Sloth moths are thought to get nutrients from the secretions of the sloths' skin and the algae present on the fur, as well as protection from avian predators.[1]

Some individual three-toed sloths have been recorded carrying more than 120 moths in their fur. Two-toed sloths are recorded as harbouring lower populations. Several different moth species may coexist on the same host animal.[1]

some people say that the moths eat the moss on the sloth but no. theres no moss on the sloth. there is algae on the sloth. and also mostly it seems they eat the sloth leavins of various kinds

on the algae:

Milla Suutari and colleagues found that the predominant algae inhabiting sloth fur was Trichophilus welckeri. It is passed directly from mother to offspring and young sloths gain the algae and other parasites by the time they are a few weeks old. This species of algae is host specific and has not been found to occur in any other environment. This finding adds strong support to the hypothesis that there is a co-evolutionary relationship between the sloths and the algae of the genus Trichophilus, which may well only exist as a symbiont.

special algae just for sloths.

but its not just sltohs and algae! there are beetles!

Beetles form a prominent portion of the arthropod community associated with sloth and sloth dung. A number of species of the coprophilous family Scarabaeidae are associated with three-toed but not two-toed sloths. The populations of these beetles can be quite large, in one case more than 980 beetles of the species Trichilium adisi were found in the fur of a single sloth. Beetles of the genus Uroxys have been recorded from sloths in Bolivia, Brazil, Colombia and Panama.[1]

Beetles appear to congregate preferentially in specific parts of the body. For example, scarab beetles occur near the elbow or on the flanks behind the knees buried deep inside the fur, while those of Trichilium spp have been found in the underfur of the lower back and thighs of Bradypus torquatus. Beetle larvae and some adult beetles use sloth dung for feeding. The population of beetles varies and the seasonal factors affecting the population size are yet to be ascertained.[1]

a little ecosystem just on the sloth... i wonder if other organisms filled this role before the sloth. arboreal dinosaur with bugs in its feathers!

All animal species (and a couple algae) that have kept the same scientific name since Linnaeus

The first work of taxonomy that is considered as having any scientific authority for animal species was the 10th edition of Linnaeus' Systema Naturae, published in 1758. (Also a book on spiders called Aranei Suecici, published one year before.) That's the foundational text of the binominal system of nomenclature of species still in use today. Since then most of Linnaeus' original species (4379 species, of which 185 mammals, 554 birds, 217 "amphibians" (including reptiles and cartilaginous fish), 379 fishes, 2104 "insects" (including various arthropods, of which 664 are beetles and 543 are moths & butterflies crammed into only 3 genera), and 940 "worms" (including basically all other invertebrates, and even some protists and algae)) have been dismembered, renamed, or at least moved to different genera (e.g. the house sparrow went from Fringilla domestica to Passer domesticus).

Here is a list of all of Linnaeus' original species from 1758 that still retain their original name. I believe they are 484 in total.

Our colleague and sloth researcher Gaston Giné is looking for students (biology and related areas) interested in doing a master's degree in developing projects that use such technologies to understand how local and landscape factors influence the occurrence, abundance and/or behavior of the arboreal mammals (sloths, porcupines, primates) in the cacao region from southern Bahia, Brazil.

The Ecology and Biodiversity Conservation graduate program from the University of Santa Cruz vacancies (doctoral and master) is open to apply until September 10.

Here’s my illustration of a pair of Nothrosiren prorrhinus, a descendant of the brown-throated three-toed sloth (Bradypus variegatus) which is one of the surviving mammals in my Splatoon headcanon! These sloths converged on the lifestyle of early Thalassocnus species, being generalist grazers feeding on seagrasses close to shore. They are on average 2.1 meters in length, and are widespread on most of the eastern coasts of Central and South America.

Happy #InternationalSlothDay!

George Edwards’ male Pale-throated Sloth (Bradypus tridactylus) from The Naturalist’s Miscellany Vol. 1, 1789, looking rather offended! This is probably because it read the rude things being written about it in the accompanying text:

“So extraordinary is the union of awkwardness and ugliness in this uncommon creature, that it has generally been regarded as one of the most striking examples of animal deformity.” 🤨

“A celebrated naturalist, the Count Buffon, will not allow this creature to have any share in contributing to the general beauty in the chain of beings, but regards it as an ill-constructed mass of deformity, created only for misery….” ☹️

“With submission, however, to this lively naturalist, I should not hesitate to believe that the sloth, not withstanding this appearance of wretchedness and deformity, is as well-fashioned for its proper modes and habits of life, and feels as much happiness in its solitary and obscure retreats, as the rest of the animal world of greater locomotive powers and superior external elegance.” 🤷🏻‍♀️

Slo the Growth

Bigger isn’t always better. Take any given species and as body size increases so does cancer risk. But this rule doesn’t hold between species. Researchers investigate why by studying the genomes of existing mammals and the fossils of extinct mammals, collecting data on body mass and lifespan to mathematically calculate cancer risk. Charting species evolution, they found that before a species evolved to become bigger, genes involved in preventing tumour formation were duplicated. This not only occurred in elephants and their ancestors but also in sloths (pictured), anteaters, armadillos and their ancestors. Although modern-day sloths are small, their ancestors were some of the largest land-dwelling animals of their time. This group, collectively called Xenarthrans, all have a low calculated cancer risk. When investigating the evolution of cancer risk, it's therefore helpful to study both existing large mammals and those descending from extinct large mammals, such as the humble sloth.

Perezosos-Los folívoros-Folivora- o filófagos (Phyllophaga)

Los folívoros (Folivora) o filófagos (Phyllophaga) son un suborden de mamíferos placentarios del orden Pilosa, comúnmente conocidos como perezosos o pereza. Son animales neotropicales de variado tamaño endémicos de las selvas húmedas de América Central y América del Sur . Las especies actuales se pueden clasificar en dos géneros: los perezosos de tres dedos (Bradypus, Bradypodidae) y los perezosos de dos dedos (Choloepus, Choloepodidae), pero se conocen más de 50 géneros

if you could be any type of land mammal what land mammal would you be

This has been in my inbox for like a week because I needed time to think about this and I had to be in the right headset. I’m not including typical pets (dogs especially) because it would be too man. But I think I have my pick:

Bradypus crinitus

They were discovered very recently in 2022. They’re from a forest in Brazil and we’re known as just the maned sloths, but the coconut heads of this guy showed that there’s two versions

Fennec Fox

I recently have been a big fan of foxes. Probably my favorite fox is the Fennec Fox. It’s the smallest fox species

Bush Baby

Ngl, the name makes me laugh, it’s pocket sized, and hehe funny eyes. That’s really it

Capybara

No explanation needed

Dik-Dik

Funky lil guy who has a funny name

Jerboas

FUCKING WHAT ELSE CAN YOU ASK FOR???? LOOK AT THIS MAN!

Lemmings

LOOK AT HIM!! LOOK!!!

Pangolin

Once again, self explanatory
