Three-Toed Sloth
- bradypus variegatus
By: C.M.Shorter
The Three-Toed
Sloth, one of three surviving
species of Sloths in the family Bradypodidae, are the slowest
moving mammals in the world. All three Sloth species are believed
to be descendents of true "Tree-Dwelling" Sloths and
considered more common than their arboreal relatives, the Two-Toed
Sloth. Easy to distinguish in appearance by the shape and coloring
of their faces, Three-Toed Sloths have an orbital shaped face
with suborbital stripes extending horizontally which outline
the ocular area of the face. These facial markings make it appear
almost as if Three-Toed Sloths are smiling all the time. Also,
the Three-Toed Sloth has a nose that is slightly smaller than
that of the Two-Toed Sloth whose snout has an almost "pig-like" appearance
and forearms that are substantially longer. Both species have
long hook-like claws on both their forefeet and hind feet, move
at an exceptionally slow pace and spend most of their lives hanging
upside down! All Sloths have three toes, even Two-Toed Sloths!
However, they have only 2 front claws whereas the Three-Toed
Sloth has 3 of these long, hook-shaped claws.

Sloths are found in the same biological family as Armadillos and Anteaters in a group of animals known as edentates (toothless
mammals). Sloths do have cheek teeth but are lacking incisors
and canines and they also make use of their very hard lips to
help tear up foraged food. Like the Two-Toed
Sloth they are medium
sized animals typically achieving weights of between 9-20 lbs.
with body length anywhere from 21-29 inches. Another anatomical
differences between the two Sloth species is Three-Toed Sloths
have short stubby tails and nine vertebrae.
We have had
the privilege to work with Sloths first-hand. Otter
John, who
many of you may know through our TigerHomes
DVD Educational Series, now has resident Sloths
at his first-class exotic animal facility, Wild
Florida Production Company. John has worked
with everything from Leopards, Tigers, Cougars, Lynx,
Bobcats, Monkeys, Lemurs, Otters,
Raccoons, Coatis, Kinkajous, Bats,
Spiders, Scorpions, Crocodiles, Alligators,
Caimans, Cobras,
Vipers, Iguanas, Tortoises,
Parrots, Hawks,
Eagles, Falcons,
Owls and Crocodile
Monitors but is known to be partial to Otters
- hence his name "Otter John".
