[9]. Although capable of living in saline environments, this species is rarely found in saltwater, but occasionally inhabits deltas and brackish lakes. The skin coloration helps with camouflage during its nocturnal hunts, but may also help absorb heat (see thermoregulation ). Habitat: C. crocodilus can be found in a variety of habitats from rivers, creeks, lagunas and estuaries in forest or savannah areas to bogs and brackish mangrove swamps in coastal areas (16, 31, 377, 531, 599). The Black Caiman is the largest living species of caiman, capable of reaching 16.5 feet long and reaching over a thousand pounds! Both indiscriminate slaughter and blanket prohibitions minimize the potential contribution of the species as an exploitable resource. Its population is very small and it can only be found in freshwater environments in Colombia and Venezuela, in particular the Orinoco river and its tributaries. … The freshwater crocodile, also known as the Australian freshwater crocodile, Johnstone's crocodile or colloquially as freshie, is a species of crocodile endemic to the northern regions of Australia. Desiccated hatchlings and young are often sold as tourist souvenirs. They first appeared 95 million years ago in the Late Cretaceous period and are the closest living relatives of birds, as the two groups are the only known survivors of the Archosauria. They also have extremely sharp teeth and the Black Caiman is a protected species in some places or have laws securing their future.

The order Crocodilia includes the true crocodiles, the alligators and caimans, and the gharial and false gharial. She lays a clutch of eggs, usually at peak flooding, which is July-August in the llanos (377, 562) and January-February in the Colombian Amazon (377) and the Pantanal de Mato Grosso (140), although this is apparently not the definitive pattern for all sites (377, 599). Large prey can include other species of caiman, deer, peccaries, tapirs, anacondas, giant otters, [27] and domestic animals including pigs, cattle, horses and dogs. Foth, C., Bona, P., & Desojo, J. It is recommended that animals hunted for their skins also be eaten to increase the nutritional and economic contribution of the species (498). Breeding occurs from May to August and 14–40 eggs are laid in July and August. A broader sense of the term crocodile, Crocodylidae that includes Tomistoma, is not used in this article. During the 65-84 day incubation period (various authors), the female guards the nest. [33] Compared to the smaller caiman species, the black caiman more often hunts terrestrially at night, using its acute hearing and sight. At the end of the dry season, the females start to build their nests of soil and vegetation.

This enables them to see and breathe while the rest of their bodies are underwater. [28] [29] Where capybara and white-lipped peccary herds are common, they are reportedly among the most common prey item for large adults. It has been listed as Least Concern on the IUCN Red List since 1996.

The female then builds her nest - a mound of earth and plant matter, some 40 cm high and at least 1 m in diameter - on a site near water but not subject to flooding, often building over an earlier nest (31, 140). However, specimens exceeding 6.1 m (20 ft) in length and weighing up to 1,089 kg (2,400 lb) have been recorded. The trade in black caiman leather peaked from the 1950s to 1970s, when the smaller but much more common spectacled caiman (Caiman crocodilus) became the more commonly hunted species. More so than even otters and anaconda, jaguars and black caiman arguably sit atop this food chain. The total maximum length reported by Medem (377) was 240 cm for males and 173 cm for females, with maximum weights of 45 kg for males and 19 kg for females. At the start of the wet season (May – June), the caiman lays between 30 – 60 eggs. He is on the Toucan Island. Courtship and mating coincide with the onset of the rains. [5] It is a generalist and apex predator, potentially capable of taking any animal within its range, including other predators. Size helps the Black Caiman a lot, as its size can intimidate potential threats. Full-sized adults also prey on mammals, semi-aquatic or aquatic reptiles, and birds. "A preliminary analysis of worldwide crocodilian attacks". Most of the prized crocodilians are endangered species (Table 23) in urgent need of protection and recovery measures such as strictly protected areas or captive breeding.
