List Of Mammals Of The United States - List Of Animals That Are Mammals

About 490 species of mammals are recorded in the United States. This list 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.

Some species are identified as indicated below:

(A) - Accidental
(E) - Extinct
(Ex) - Extirpated (extinct in the USA, but exists elsewhere in the world)
(I) - Introduced

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

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

and the Endangered Species Act:

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

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.

Family: Didelphidae (American opossums)
- Subfamily: Didelphinae
  - Virginia opossum Didelphis virginiana LC

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 is found in the United States.

Family: Dasypodidae (armadillos)
- Subfamily: Dasypodinae
  - Nine-banded armadillo Dasypus novemcinctus LC

Order: Rodentia (rodents)

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 45Â kg (100Â 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.
