The Everglades Critter is a term used to describe the three species of reptiles that inhabit the Florida Everglades: CROC, Gator, and Alligator. CROC is a four-letter word for a crocodile, a large reptile with a long snout and a thick hide. Gator is a five-letter word for an alligator, a large reptile with a wide snout and a tough hide. Alligator is a nine-letter word for an alligator, a large reptile with a broad snout and a tough hide. All three species are native to the Everglades and can be found in the wetlands, rivers, and lakes of the region.
