List of mammals of Ireland

This is a list of the 60 mammal species recorded in Ireland. A new Red List of Irish terrestrial mammals was published in 2009 and all 26 terrestrial species native to Ireland, or naturalised in Ireland before 1500, were assessed. Of these, one was found to be regionally extinct (grey wolf Canis lupus), one achieved a threat status of Vulnerable (black rat Rattus rattus), three were found to be Near Threatened (Leisler's bat Nyctalus leisleri), otter (Lutra lutra) and red squirrel (Sciurus vulgaris)), one was data deficient (Brandt's bat Myotis brandtii) and the remaining 20 were of least concern.[1]

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

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.
RE Regionally Extinct The species is extinct in the wild in the region.
CR Critically Endangered The species is in imminent risk of extinction in the wild. At this point, action is taken to preserve the habitat.
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.

Subclass: Theria

Infraclass: Eutheria

Order: Rodentia (rodents)

Red squirrel

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: Lagomorpha (lagomorphs)

European rabbit

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)

West European hedgehog

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)

Eurasian Pygmy Shrew

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

Order: Chiroptera (bats)

Daubenton's bat
Brown long-eared bat

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)

North Atlantic right whale
Humpback whale diving.
Beluga
Harbour porpoise
Risso's dolphin
Bull killer whale

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)

Stoat
Grey seal

Carnivorans include over 260 species, the majority of which eat meat as their primary dietary item. They have a characteristic skull shape and dentition.

Order: Artiodactyla (even-toed ungulates)

Red deer

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.
