Animals in Brazil

94 mammal species are recorded in Brazil in this dataset, 24 of them in a threatened Red List category. Brazil sits in South America, where 232 species are recorded in total. Every species below is listed because the range description of its IUCN Red List assessment names Brazil.

They belong to 28 families, the best represented being Phyllostomidae (17), Cricetidae (16), Atelidae (8). By Red List category: 4 Critically Endangered, 7 Endangered, 13 Vulnerable, 6 Near Threatened, 60 Least Concern, 4 Data Deficient.

These counts come from the text of each assessment rather than from an official country checklist, so a species whose assessment names a region without naming Brazil is missing here, and a wide-ranging animal is counted in every country it crosses. All 94 of them have a full written profile.
