This is a list of the mammal species recorded in the Seychelles. Of the mammal species in the Seychelles, two are critically endangered and two are vulnerable.[1]
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:
EW | Extinct in the wild | Known only to survive in captivity or as a naturalized populations well outside its previous range. |
CR | Critically endangered | The species is in imminent risk of extinction in the wild. |
EN | Endangered | The species is facing an extremely high risk of extinction in the wild. |
VU | Vulnerable | The species is facing a high risk of extinction in the wild. |
NT | Near threatened | The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future. |
LC | Least concern | There are no current identifiable risks to the species. |
DD | Data deficient | There is inadequate information to make an assessment of the risks to this species. |
Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories:
LR/cd | Lower risk/conservation dependent | Species which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued. |
LR/nt | Lower risk/near threatened | Species which are close to being classified as vulnerable but are not the subject of conservation programmes. |
LR/lc | Lower risk/least concern | Species for which there are no identifiable risks. |
Order: Sirenia (manatees and dugongs)
Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered.
- Family: Dugongidae
Order: Chiroptera (bats)
The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight. Bat species account for about 20% of all mammals.
