Key Deer photographed on Big Pine Key by Ken Araujo.

Key deer, an endangered species, used to roam the Keys (yes, they can swim) from Key West to Grassy Key, a 60-mile span. Now they only reside only on Big Pine and No Name keys. It's illegal to feed them, but people do it all the time. And I can't say I blame them. At full size they're about the size of a full grown dog.
