Kingdom: Animalia
Phylum: Chordata Class: Reptilia Order: Crocodylia Family: Alligatoridae Genus: Caiman Species: crocodilus Description: The spectacled caiman got its name from the bony ridge between its eyes which give it the appearance of wearing a pair of glasses. These caiman can grow up to approximately nine feet in length, with females being of smaller size than males. They have a stout snout, and a triangular ridge of skin atop each eye which give the appearance of a type of 'eye brow'. Mature individuals are olive-green with faint black spots and banding on their tails, this coloration is usually more distinct in younger individuals. Its coloration overall is quite variable, with some individuals having different coloration, sizes, and skull shape - these features have led to distinction between three subspecies of spectacled caiman.
Range and Biology:
This species is widely distributed compared to other crocodilians. The spectacled caiman and its subspecies can be found in Mexico, Peru, Brazil, Venezuela, Columbia, Bolivia, and Ecuador - it has also been introduced as a nonnative species in Cuba, Puerto Rico, and Florida, USA. Theses animals thrive in all lowland wetland and riverine habitats, preferring bodies of still water like lakes, ponds, and marshes. They are also tolerant to moderate salinity. The caiman is highly adapted for water life. It is a superb swimmer and aquatic predator. The adult caiman feed on fish, amphibians, reptiles, and water foul - particularly large individuals have also been know to take on mammals including deer and pigs! In dry conditions when food sources are scare this species is also known to cannibalize smaller individuals.
In Florida:
The spectacled caiman was first sighted in Florida in 1960, and span across two counties in the state. It poses threat to a variety of native vertebrates and competes for food and space with the native American alligators. They are presumed to have been released or escaped from the pet trade, and can be found in Broward and Dade counties throughout marshes, lakes, ponds, and canals. These crocodilian are susceptible to colder weather, which has confined them from moving further north. There have been efforts to remove the caiman populations, and in 2001 a nest of 41 eggs was found and collected, and 39 of those eggs hatched in captivity. Since 1970 there have been no reports of breeding, however the populations are still present.
