List of mammals of Bangladesh

This is a list of the mammal species recorded in Bangladesh. There are eighty-nine mammal species in Bangladesh, of which three are critically endangered, twelve are endangered, sixteen are vulnerable, and four are near threatened.
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:
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: Carnivora (carnivorans).
There are over 260 species of carnivorans, the majority of which eat meat as their primary dietary item. They have a characteristic skull shape and dentition.
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: Chiroptera (bats).
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: 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: Pholidota (pangolins).
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: Primates.
The order Primates contains humans and their closest relatives: lemurs, lorisoids, monkeys, and apes.
Order: Proboscidea (elephants).
The elephants comprise three living species, and are the largest living land animals.
Order: Rodentia (rodents).
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 (100 lb).
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: Soricomorpha (shrews).
The "shrew-forms" are insectivorous mammals. The shrews and solenodons closely resemble mice while the moles are stout-bodied burrowers.
Extirpated.
The following species are locally extinct in the country:
