Animals in Ecuador
60 mammal species are recorded in Ecuador in this dataset, 18 of them in a threatened Red List category. Ecuador 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 Ecuador.
They belong to 23 families, the best represented being Phyllostomidae (21), Cricetidae (6), Didelphidae (4). By Red List category: 1 Critically Endangered, 9 Endangered, 8 Vulnerable, 4 Near Threatened, 37 Least Concern, 1 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 Ecuador is missing here, and a wide-ranging animal is counted in every country it crosses. All 60 of them have a full written profile.
