In Massachusetts, a C. crocodilus was collected from a swamp in Taunton, Bristol County, in 1989, and another from a wetland in Plainfield, Hampshire County, in 1991. Those were just two of the very rare occassions of a crocodile encounter in the state.
You aren't generally likely to see crocodiles in Massachusetts or in any other states apart from Florida and probably South Carolina.
Of the 23 different species of crocodilians in the world, 2 species are native to the United States, and south Florida is the only place where both of these species coexist.
Common environments for crocodiles include mangrove swamps, creeks, lagoons on coasts, mouths of rivers, lakes, damp wetlands, coves and ponds.
Like most reptiles, crocodiles spend the large part of their lives in inactivity. For the crocodile, this inactivity may be spent in one of three ways: basking on the bank, resting in a burrow, or waiting for prey.
