List of mammals of Ireland
This is a list of the mammal species recorded in Ireland. There are 59 mammal species 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.
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||RegionalExtinct||The species is extinct in the wild in the region.|
|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.|
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).
- Suborder: Sciurognathi
- Family: Sciuridae (squirrels)
- Family: Cricetidae
- Family: Muridae (mice, rats, etc.)
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.
- Family: Leporidae (rabbits, hares)
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.
- Family: Erinaceidae (hedgehogs)
Order: Soricomorpha (shrews, moles, and soledons)
The "shrew-forms" are insectivorous mammals. The shrews and soledons closely resemble mice while the moles are stout bodied burrowers.
- Family: Soricidae (shrews)
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.
- Family: Vespertilionidae
- Family: Rhinolophidae
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.
- Suborder: Mysticeti
- Family: Balaenidae
- Family: Balaenopteridae
- Suborder: Odontoceti
- Superfamily: Platanistoidea
- Family: Monodontidae
- Family: Phocoenidae
- Family: Physeteridae
- Family: Kogiidae
- Family: Ziphidae
- Subfamily: Hyperoodontidae
- Family: Delphinidae (marine dolphins)
- Genus: Delphis
- Short-beaked Common Dolphin Delphinus delphis
- Genus: Tursiops
- Bottlenose Dolphin Tursiops truncatus DD
- Genus: Stenella
- Striped Dolphin Stenella coeruleoalba LR/cd
- Genus: Lagenorhynchus
- Genus: Grampus
- Risso's Dolphin Grampus griseus DD
- Genus: Orcinus
- Orca Orcinus orca LR/CD
- Genus: Globicephala
- Pilot whale Globicephala melas LR/LC
- Genus: Pseudorca
- False Killer Whale Pseudorca crassidens
- Genus: Delphis
- Superfamily: Platanistoidea
Order: Carnivora (carnivorans)
Carnivorans include over 260 species, the majority of which eat meat as their primary dietary item. They have a characteristic skull shape and dentition.
- Suborder: Caniformia
- Family: Canidae (dogs, foxes)
- Family: Mustelidae (mustelids)
- Family: Odobenidae
- Family: Phocidae (earless seals)
- Genus: Halichoerus
- Grey Seal Halichoerus grypus LR/LC
- Genus: Phoca
- Common Seal Phoca vitulina LR/LC
- Genus: Erignathus
- Bearded Seal Erignathus barbatus LC/RC
- Genus: Pusa
- Ringed Seal Pusa hispida LC/RC Migrant. Very occasional.
- Genus: Pagophilus
- Harp Seal Pagophilus groenlandicus LC/RC Migrant. Very occasional.
- Genus: Cystophora
- Hooded Seal Cystophora cristatus VU Migrant. Very occasional.
- Genus: Halichoerus
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.
- Family: Suidae (pigs)
- Family: Cervidae (deer)
- Subfamily: Cervinae
- Subfamily: Capreolinae
- Family: Bovidae
- This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD). The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institute, or University of Michigan where no Wikipedia article was available.
