Animals in Brunei
18 mammal species are recorded in Brunei in this dataset, 7 of them in a threatened Red List category. Brunei sits in Asia, where 324 species are recorded in total. Every species below is listed because the range description of its IUCN Red List assessment names Brunei.
They belong to 9 families, the best represented being Sciuridae (5), Pteropodidae (3), Felidae (2). By Red List category: 1 Critically Endangered, 4 Endangered, 2 Vulnerable, 9 Least Concern, 2 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 Brunei is missing here, and a wide-ranging animal is counted in every country it crosses. All 18 of them have a full written profile.
