|Maned 3-toed Sloth (Bradypus torquatus)
The Maned 3-toed Sloth is a Brazilian endemic found in the Atlantic Rain Forest remnants in Bahia, Espírito Santo and Rio de Janeiro. It is classified as Endangered given the rapid disappearance of its habitat.
It is similar to the Brown-throated 3-toed Sloth Bradypus variegatus but has a tan-coloured head and a black "mane" of long hairs projecting as plumes over the shoulders. It's behaviour is also similar to that described on the Brown-throated 3-toed sloth page.
