The sloths in these photos are Hoffmann's two-toed sloths. If you look closely, you can see that they have only two toesâor fingersâon each front foot. (Some other sloth species have three front toes.) But those toes are very important! Their long, curved claws keep sloths firmly attached to tree branches. And those claws are their only defense against predators.
Today, there are 2 genera of sloths: three toed sloths (Bradypus) and two toed sloths (Choelepus), each one in its own family (thus, not so closely related). All sloths have three digits on the rear limbs and three, respectively two, in the two genera, as their names point.
