Southern maned sloth range |
The southern maned sloth (Bradypus crinitus) is a three-toed sloth species.
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.
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]
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). [4]
The sloth received Gray's old name, Bradypus crinitus. [3] The name crinitus means 'hairy', referring to its coconut-like head. [5]
