Black Caiman Fact File

Appearance

The black caiman is the largest member of the alligator family. Males are larger than females. On average this species grows to lengths of between 4 and 6m (13-20ft). They can reach weights of up to 300kg (660lbs).

Adult caimans retain the bright markings on their skin in to adulthood. This pattern of yellowish strips and spots cover the rest of the dark colored skin from which their name is derived.

Their eyes and nostrils sit on top of the head allowing them to sit out the water so they can see and breathe while their body remains hidden.

The patterning of their skin made the skin highly prized and increased hunting pressure on them.

Diet

Black caimans are carnivores. Fish comprise the main part of their diet but mammals, amphibians, insects and crustaceans may also be eaten.

They are capable of taking down large items such as capybara, buffalo or large snakes. In areas where they live alongside humans they will also feed on domestic livestock.

Reproduction

Nesting takes place during the dry season from September through December.

The nest is a mound and the female uses her hind legs to dig the egg chamber. Females deposit between 30 and 65 eggs in to the nest.

Most females will defend their eggs and may provide some care for the hatchlings once they emerge from their eggs. Incubation lasts between two and three months with the variance being attributed to nest temperature.

The eggs face a number of threats including predation and flooding of the nest.

Groups of hatchlings will form and are known as pods. These may be siblings or from multiple nests.

Behavior

Most of their day is spent in the water. At night they may come ashore. Nesting and basking occur on the shoreline.

Predators and Threats

Adults are generally considered the apex predator in their environment but may be consumed by jaguars and large snakes such as the anaconda.

This species was driven to extinction across much of its range as they are prized for their skin. They retain their bright coloration in to adulthood. It is thought that over 90% of the population may have been hunted over the past 100 years.
