The lack of tail and external ears, a slightly rounded head, and a blunt nose are the features used to identify the Pale-throated Three-toed Sloth (Bradypus tridactylus). It is found in the tropical rainforest in southern Central America to north-eastern Argentina in trees with dense foliage. The hair is long and coarse, with some patches of small visible algae, giving it a greenish appearance. Males are identified by an orange or bright yellow patch on their backs. This sloth is arboreal, solitary, existing only inside the forest. It is also slow-moving, an excellent swimmer, and is mostly found hanging upside down. Though it can stand on its feet, it cannot walk on them.
