Description: Similar to the American Alligator, the
Black Caiman is the largest carnivore found in the Amazon
Rainforest and the second largest reptile in existence
(only the Saltwater Crocodile is larger). Growing to
a maximum length of nearly 20 feet, and weighing up to
2,000 pounds, the Black Caiman is black in coloration
with light white or yellow banding on the sides and brown
or gray banding on the lower jaw. The black coloration
is an effective camouflage for this nocturnal hunter
and may help it absorb heat.
Diet: The Black Caiman is an opportunistic hunter that
preys more heavily on fish than alligators and reptiles.
Caimans take large quantities of piranhas and other Amazon
River fish, as well as mollusks, catfish, and some mammals
and birds.
Habitat and Range: The Black Caiman is limited to slow-moving
freshwater lakes, rivers, swamps, marshes, and wetlands
of the Amazon region in eastern and northeastern South
America.
Breeding: Females lay between 20-40 eggs anytime during
the Amazon Dry Season, which runs from September to December.
The female remain close to the nest site but will not
actually defend it. After two or three months, the hatchling
emerge and form groups called pods. Females will sometimes
carry the hatchlings in her mouth to the nearby water
source. Black Caimans have slow reproductive rates and
the female only breeds once every two or three years.
Status: Populations of Black Caimans have been in serious
decline for several decades. The current population is
thought to be only a fraction of historical populations.
Caimans are hunted extensively for their skin and are
negatively impacted by continued deforestation in the
Amazon region.
