FLORIDA WILDLIFE: American Crocodiles Numbers Have Increased From 300 To 1,500

Florida Fish and Wildlife Conservation Commission – The American crocodile is a success story as their numbers have increased from 300 to 1,500.
American crocodiles (Crocodylus acutus) are a shy and reclusive species. They live in coastal areas throughout the Caribbean, and occur at the northern end of their range in south Florida.
They live in brackish or saltwater areas, and can be found in ponds, coves, and creeks in mangrove swamps. They are occasionally being encountered inland in freshwater areas of the SE Florida coast as a result of the extensive canal system.
Like alligators, crocodiles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Crocodiles control their body temperature by basking in the sun, or moving to areas with warmer or cooler air or water temperatures.
A basking crocodile may be surprised by an approaching person and quickly (and noisily) enter the water. This behavior might startle the person, but it should not be misunderstood. Crocodiles would normally enter the water quietly; splashing away indicates that the crocodile is frightened.
Crocodiles can also be seen sunning with their mouths open, or “gaping.” This behavior is also related to regulating their body temperature, and does not mean that the crocodile is acting aggressively toward people.
