List of mammals of Chad

From Wikipedia, the free encyclopedia

This is a list of the mammal species recorded in Chad. There are 136 mammal species in Chad, of which four are critically endangered, two are endangered, eight are vulnerable, and two are near threatened. One of the species listed for Chad can no longer be found in the wild.[1]

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

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.

Order: Afrosoricida (tenrecs and golden moles)

[edit]

The order Afrosoricida contains the golden moles of southern Africa and the tenrecs of Madagascar and Africa, two families of small mammals that were traditionally part of the order Insectivora.

Order: Tubulidentata (aardvarks)

[edit]
Aardvark

The order Tubulidentata consists of a single species, the aardvark. Tubulidentata are characterised by their teeth which lack a pulp cavity and form thin tubes which are continuously worn down and replaced.

Order: Hyracoidea (hyraxes)

[edit]
Cape hyrax

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: Proboscidea (elephants)

[edit]
African bush elephant

The elephants comprise three living species and are the largest living land animals.

Order: Sirenia (manatees and dugongs)

[edit]

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

[edit]
Mantled guereza

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

Order: Rodentia (rodents)

[edit]

Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. Most rodents are small though the capybara can weigh up to 45 kg (99 lb).

Order: Lagomorpha (lagomorphs)

[edit]

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: Erinaceomorpha (hedgehogs and gymnures)

[edit]

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)

[edit]

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

Order: Chiroptera (bats)

[edit]

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.

Order: Pholidota (pangolins)

[edit]

The order Pholidota comprises the eight species of pangolin. Pangolins are anteaters and have the powerful claws, elongated snout and long tongue seen in the other unrelated anteater species.

Order: Carnivora (carnivorans)

[edit]
Sand cat
Lion
Common genet
Banded mongoose
Spotted hyena
Fennec fox

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

Order: Perissodactyla (odd-toed ungulates)

[edit]
Black rhinoceros

The odd-toed ungulates are browsing and grazing mammals. They are usually large to very large, and have relatively simple stomachs and a large middle toe.

Order: Artiodactyla (even-toed ungulates)

[edit]
Northern giraffe
Dama gazelle
Oribi
Bushbuck

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.
