Caiman latirostris
The yacaré overo or yacaré ñato (Caiman latirostris) is a species of crocodile in the Alligatoridae family. It is endemic to the subtropical and tropical regions of South America, which can exceed three meters in length. Its name derives from the coloration of diffuse spots between intense green and pale gray that characterizes it. It is less widespread than its close relative, the black alligator, with whom it shares a habitat.
Intensively hunted for decades, it is registered in Appendix II of the CITES list of protected species.
Common names
It is often known as “yacaré overo”, “yacaré ñato” or “yacaré with a wide snout”; also as "broad-snouted caiman", or "Brazilian caiman".[citation needed]
Description
The alligator overo exceeds two and a half meters in length in the adult state, although specimens of this size are rare. There is marked sexual dimorphism, with females being noticeably smaller. In addition to its coloration, it is distinguished from similar species by its stout, short snout, as broad as its head, and the larger size of the protective plates on its neck. It can reach a mass of 90 kg (weight 882 N).[citation needed]
It has variable coloration, combining intense green with more greyish tones; juveniles show a characteristic striped pattern, occasionally preserved in adults. The pigmentation has excellent mimetic properties, making it virtually invisible in the densely vegetated areas where it inhabits. The belly goes from a yellowish or even gray color.
Distribution and habitat
The overo yacaré inhabits swampy and lacustrine regions of Bolivia, Brazil, Argentina, Paraguay, and Uruguay, especially the Amazon, Paraguay, and Paraná river basins. It prefers areas with intense vegetation and a tropical climate, which favor hunting and reproduction, although it can survive in more temperate and drier climates than other species; specimens have been reported in artificial ponds for livestock up to 22° south latitude. The most important population centers are found in the Brazilian Pantanal and in the Iberá system in Argentina.[citation required]
Behavior
The diet of the alligator overo is exclusively carnivorous; eats mainly snails, other molluscs and crustaceans. Catch other reptiles and small mammals.[citation needed]
Often guard young for several months. The hatchlings will remain in small watercourses until they get stronger.[citation needed]
Juveniles have a high rate of natural mortality; Its main predators are birds of prey, especially the caracara, the crab-eating hawk and the jabirú. However, hunting for the use of the skin —more delicate and less leathery than that of other species— has been the main element in the intense reduction in the number of the species. It is still caught on a small scale for consumption of its meat and eggs.[citation needed]
There are several alligator breeding projects on farms in Brazil and Argentina; part of the production is reintegrated into the environment, and the rest is slaughtered for commercial exploitation, it, historically, was directed to the use of the animal's leather (destined for the production of footwear and leather goods), also, in recent years, its meat has been commercialized.[citation needed]
