The three-toed sloth ( Bradypus ) is about the size of a house cat, with a dense, furry coat and yellowish face. It has three toes on the front feet and five on the hind feet. In addition to algae, its main food is the leaves, buds, and stems of Cecropia, a tropical relative of the mulberry. The somewhat larger two-toed sloth ( Choloepus ) has very long hair. It eats a less restricted vegetarian diet. Sloths move sluggishly but can strike swiftly and powerfully if attacked. Huge ground sloths (see megatherium ) are extinct forms.
Sloths are classified in the phylum Chordata , subphylum Vertebrata, class Mammalia, order Edentata, families Bradypodidae and Megalonychidae.
