Costa Rican Sloth

A sloth in Costa Rica in a rare moment of activity. A little fun fact about sloths: they are designed to conserve energy. For example, their claws are attached to the bones in their arms so that it costs zero muscle energy to hang down a tree. People who used to shoot them for their meat would have to climb the tree to pick up the dead sloth, since it will never fall. The utlimate proof that nature has a sense of humour.
