Its cry sounds like "ay ay", much like that of a woman screaming.

The female of the species emits a loud, shrill scream during the mating season to attract males.The flexible head of this animal can rotate up to 90 degrees. Due to the specific shape of its mouth, the Brown-throated sloth seems to smile constantly.So when it's cold, the animal cannot shiver in order to warm up. Muscles make up only 25% of a sloth's body.They are known to use breaststroke style, just like humans. These accomplished swimmers drop themselves off branches into rivers to swim.These sloths practice two types of resting: "awake-alert" - this is when they rest with open eyes and blink and "behavioral sleep" - this is when they are suspended from a tree with their eyes closed.They eat only leaves, including those of Cecropia, Ceiba, Elizabetha, and Hevea. Depending on habitat, population densities of anything from 1.7 to 221 per square kilometre (4.4 to 570 /sq mi) have been reported. In this patch, they possess scent-marking glands, which are used to attract receptive females. Pale-throated sloths are solitary, herbivorous animals that spend almost their entire lives in trees. Males of this species are identified by a bright yellow or orange-colored marking between their shoulders.Algae, in turn, serve as camouflage, helping them escape predators.

These animals allow algae to live in their fur, providing it with the required moisture. Algae, growing on their fur, do not occur anywhere else.
