“List of mammals of Yemen”的意思、由来-开放百科全书

This is a list of the mammal species recorded in Yemen. There are sixty-nine mammal species in Yemen, of two are endangered, seven are vulnerable, and three are near threatened. Two of the species listed for Yemen are extinct.^[1]

The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:

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:

Subclass: Theria

Infraclass: Eutheria

Order: Hyracoidea (hyraxes)

The hyraxes are any of four species of fairly small, thickset, herbivorous mammals in the order Hyracoidea. About the size of a domestic cat they are well-furred, with rounded bodies and a stumpy tail. They are native to Africa and the Middle East.

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.

Order: Primates

The order Primates contains humans and their closest relatives: lemurs, lorisoids, monkeys, and apes.

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 45 kg (100 lb).

Order: Erinaceomorpha (hedgehogs and gymnures)

The order Erinaceomorpha contains a single family, Erinaceidae, which comprise the hedgehogs and gymnures. The hedgehogs are easily recognised by their spines while gymnures look more like large rats.

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)

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: 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.

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.
