They make their homes in bogs and mangrove swamps. Their range is coastal south Florida and the Key Islands. A croc can be anywhere from 7 to 15 feet long. An alligator has a rounded snout. A croc's snout is more pointed.
Crocodiles have a flattened head, with eyes slightly raised on top of the head.
They have short legs with heavy claws. There are 4 raised ridges on the back that merge with two atop the tail. They are generally olive-grey, with dark bands across their back and tail. These bands are hard to see in old adults. In crocodiles, the downward-pointing teeth of the upper jaw and the large 4th tooth on the bottom jaw are visible when the croc's mouth is closed.
