List of mammals of the Dominican Republic
This is a list of the mammal species recorded in the Dominican Republic. Of the mammal species in the Dominican Republic, one is critically endangered, one is endangered, three are vulnerable, and eight are considered to be extinct. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: 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: 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 . Order: Eulipotyphla (shrews, hedgehogs, moles, and solenodons). Eulipotyphlans are insectivorous mammals. Shrews and solenodons closely resemble mice, hedgehogs carry spines, while 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 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: Primates (primates). There are 190 – 448 species of living primates, depending on which classification is used. They have an opposable thumb for grasping objects. 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 – hoofed animals – which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly.
