Crab-eating Raccoon (Procyon cancrivorous)
Crab-eating raccoons eat not just crabs, but other crustaceans and plenty of fruit, too: probably just about anything they can get their paws on, really. They live in Central and South America, from Costa Rica to Argentina, and on some Caribbean islands. I think they kind of look like a summertime version of our North American common raccoons, and they are closely related, but with shorter fur for their warmer climate and slightly different coloring.
Here is a blogger’s story of an encounter with a tame crab-eating raccoon named Bandit. (She also recounts her first experience with Marmite.)
