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.
While their claws are large, sloths are herbivores, or plant eaters. They use the claws for protection rather than to kill food. The leaves they eat are hard to digest and low in nutritional value, and they have a very slow metabolism as a result. Sloths move very little and most of their movements are very slow, so as not to expend more energy than necessary.
