This pygmy three-toed sloth isn’t swimming for safety or fun. It’s most likely swimming to see if that sloth it spotted across the surf is available for a long-term relationship. Swimming—a rare sight—is the fastest way to get to a potential mate. These slow-moving vegetarians spend most of their days in the forest canopy of Isla Escudo de Veraguas, a small island off the coast of Panama. It’s the only place the rare creatures are found.
