The Broad-Snouted Caiman (Caiman latirostris) is widely distributed in theSoutherneastern South America, occupying rivers, mangroves and wetlands in Argentina,Uruguay, Bolivia, Paraguay and Brazil. In Brazil, the species is found in the Cerrado, Caatinga,Atlantic Forest and the Pampas biomes, extending from the coastalareas of Rio Grande do Norteto São Francisco and Paraná-Paraguay watersheds and reaching the Lagoa dos Patos e LagoaMirim, in the State of Rio Grande do Sul. More than 70% of the species global distribution iswithin the Brazilian territory. The extension of occurrence (EOO) in Brazil is 2,672,480.4 km2,whereas the area of occupation (AOO) is estimated to be >20.000 km2. The large distributionrange of the species and its apparent capacity to colonize anthropic environments justifies itsclassification as Least Concern (LC). However, anthropic pressures, associated with a relativelyhigh hunting perssure in cerain regions, may affect the connectivity and consequently the geneflow among populations of the species both in micro and macrogeographic scales, what shouldbe monitored.
