Habitat

American Crocodile (1)

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.

The American crocodile inhabits brackish or saltwater areas and can be found in ponds, coves, and creeks in mangrove swamps. American crocodiles occur in South Florida and also can be found in Hispaniola, Cuba, Jamaica, along the Caribbean coast from southern Mexico to Venezuela, and along the Pacific coast from Mexico to Peru. The northern end of the crocodile’s range is in South Florida. Occasionally, crocodiles are encountered inland in freshwater areas along the southern Florida coast (Distribution map data from: Krysko et al. 2011).

Behavior

American Crocodile (2)

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.

The diet of the American crocodiles primarily consists of small mammals, birds, frogs, turtles, and fish (Fishman et al. 2009).

Male crocodiles begin courting females in late January and early February. Crocodiles are ectothermic and therefore control their body temperature by basking in the sun, or moving to areas with warmer or cooler air or water temperatures. Courting rituals can be extensive, often lasting for days. Males initiate courting by quickly and consecutively performing head slaps, and the female will raise her snout and arch her tail if she is interested. The last courting ritual involves the male and female rubbing snouts and submerging under water. Nesting occurs in late April and early May. The soil nests are built on land and above high tide marks. Females will lay 20 to 60 eggs that incubate for about 85 days. When the incubation period is complete, females will dig the nest up and carry the young to water (Mazzotti, n.d.).
