List of threatened mammals of Brazil
There are more than 700 species of mammals in Brazil, and according to the Chico Mendes Institute for Biodiversity Conservation and Brazil's Ministry of the Environment, about 110 species and subspecies are threatened and one is extinct. The Brazilian definition of "threatened species" uses the same criteria and categories established by IUCN. Among the 12 mammal orders which occur in Brazil, eleven have threatened species, except Lagomorpha (which has only one species in Brazil, the Brazilian cottontail). Although the rodents have been the most diverse order of mammals, the order with most species on this list is the Primates (34 species).This list of threatened species was published in Diário Oficial da União, on December 17, 2014. Even though some species have been removed from the list, (for instance, the humpback whale), the number of threatened species has increased in comparison with the former list (which had had 69 species).
