List of mammals of American Samoa

From Wikipedia, the free encyclopedia

This is a list of the mammal species recorded in American Samoa. There are 8 mammal species in American Samoa, of which 0 are critically endangered, 1 is endangered, 2 are vulnerable, and 0 are near-threatened.^[1]

The following tags are used to highlight each species' conservation status as assessed by the IUCN:

EX	Extinct	No reasonable doubt that the last individual has died.
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.

The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals in the world naturally capable of flight. Bat species account for about 20% of all mammals.
