Several hundreds of those make their home in the cooling canals surrounding Turkey Point nuclear power plant. Turkey Point and the surrounding areas is one of only three major habitats for the American Crocodile in the U.S.  The other two are Everglades National Park and Crocodile Lake National Wildlife Refuge in Key Largo.

American crocodiles range in color from gray-yellow to brown, can grow up to 15 feet long and weigh as much as 2,000 pounds.
