Two-toed Sloth
Choloepus didactylus 
Makushi name: Kuwaran, Kîwaran, Tenupi 
Size: body=60 cm; weight=6 kg 
Description: Hangs below branch. Fur long and shaggy, brownish, darker on limbs than body. Limbs long, taper to narrow feet with bare pads; two large claws on front foot, three on hind foot. No tail. Snout piglike with large, widely spaced nostrils. Young sloth is dark brown. Eyeshine dull reddish. 
Activity: Mainly nocturnal but may be active by day; arboreal, usually in the canopy. Travels more quickly than three-toed sloth. Descends to the ground about once a week to defecate; on ground it moves awkwardly on all fours; swims well. 
Habits: Solitary. It sleeps by day in a vine tangle or shaded crotch of a tree. It moves on thin vines and lianas and seldom ascends large tree trunks. The diet consists of leaves of a variety of trees, also fruit and buds. It is usually silent and easily overlooked, but fighting males can emit piercing screams. When disturbed it is more aggressive than the Three-toed Sloth and will slash with the foreclaws or bite. 
Habitat: Mature and secondary forest. 
Signs: Look for a brown ball on a tree crotch, often easier to see at night as it descends to feed at a lower level. 
Status: Not yet recorded from Iwokrama but probably locally common. Less common than Three-toed Sloth.
