List of mammals of the United States

This is a list of about 490 mammal species recorded in the United States. It is probably incomplete. Unincorporated territories like for example Puerto Rico, Guam or Northern Mariana Islands are not covered. Mammals introduced and extinct in the Holocene except Pleistocene/Holocene boundary are included.

According to the IUCN Red List 3 of these species are critically endangered, 20 endangered, 15 vulnerable, 20 near threatened and 4 extinct.[1]

Some species are identified as indicated below:

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

EX Extinction 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 categorize 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.

(v. 2013.2, the data are current as of March 5, 2014[1])

and the Endangered Species Act:

E Endangered
T Threatened
XN, XE eXperimental Nonessential or Essential population
E(S/A), T(S/A) Endangered or Threatened due to Similarity of Appearance

(the data are current as of March 28, 2014[2])

Subclass: Theria

Infraclass: Metatheria

Order: Didelphimorphia (common opossums)


Didelphimorphia is the order of common opossums of the Western Hemisphere. Opossums probably diverged from the basic South American marsupials in the late Cretaceous or early Paleocene.They are small to medium-sized marsupials, about the size of a large house cat, with a long snout and prehensile tail.

Infraclass: Eutheria

Order: Cingulata (armadillos)


The armadillos are small mammals with a bony armored shell. They are native to the Americas. There are around 20 extant species. Only the Nine-banded armadillo one is found in the United States.

Order: Rodentia (rodents)


American beaver

Rodents make up the largest order of mammals, with over 40 percent of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be keep short by gnawing. Most rodents are small though the capybara can weigh up to 45 kg (100 lb).

Order: Lagomorpha (lagomorphs)


The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas). Though they can resemble rodents, and were classified as a superfamily in that order until the early 20th century, they have since been considered a separate order. They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.

Order: Soricomorpha (shrews, moles, and solenodons)


The "shrew-forms" are insectivorous mammals. The shrews and solenodons closely resemble mice while the moles are stout-bodied burrowers.

Order: Chiroptera (bats)

Eastern small-footed bat

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.

Order: Carnivora (carnivorans)


There are over 260 species of carnivorans, the majority of which feed primarily on meat. They have a characteristic skull shape and dentition.

Order: Artiodactyla (even-toed ungulates)


The even-toed ungulates are ungulates whose weight is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 artiodactyl species, including many that are of great economic importance to humans.

Order: Proboscidea (elephants and allies)

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.

Order: Cetacea (whales)


The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater.
