The southern maned sloth (Bradypus crinitus) is a three-toed sloth species.
Description
[edit]The southern maned sloths have flatter skulls, rounder jaws, and wider cheekbones than the northern maned sloths.[1] The species has a head that looks like a coconut.
Distribution
[edit]The sloth is endemic to Brazil's Atlantic Forest, a highly biodiverse region. Southern maned sloths were found in Rio de Janeiro and Espírito Santo.[2]
Discovery
[edit]The species was discovered by John Edward Gray in 1850, but his assertions were later dismissed, with taxonomists agreeing that the specimen, that Gray described was a B. torquatus, but the new study proves that B. critinus does indeed exist.[1] The B. crinitus separated from B. torquatus in the north by more than 4 million years of evolution.[3] B.torquatus and B. crinitus are allopatrically distributed that diverged during the Early Pliocene (period of global cooling).

Name
[edit]The sloth received Gray's old name, Bradypus crinitus.[3] The name crinitus means 'hairy', referring to its coconut-like head.[4]
