List of mammals of Great Britain

This is a list of mammals of Great Britain. The diversity of mammal fauna of Great Britain is somewhat impoverished compared to that of Continental Europe, due to the short period of time between the last ice age and the flooding of the land bridge between Great Britain and the rest of Europe. Only those land species which crossed before the creation of the English Channel and those introduced by humans exist in Great Britain.

Native (usually synonymous with "indigenous") species are considered to be species which are today present in the region in question, and have been continuously present in that region since a certain period of time. When applied to Great Britain, three possible definitions of this time constraint are:


 * a species that colonised the islands during the glacial retreat at the end of the last ice age (c. 9500 years ago);
 * a species that was present when the English Channel was created (c. 8000 years ago); or,
 * a species that was present in prehistory.

This list includes mammals from the small islands around Great Britain and the Channel Islands. There are no endemic mammal species in Great Britain, although four distinct subspecies of rodents have arisen on small islands.

The following tags are used to highlight the conservation status of each species' British population, as assessed by Natural England and The Mammal Society in a Regional Red List, following the criteria of the International Union for Conservation of Nature.

Diprotodonts
Order: Diprotodontia

Although marsupials are primarily found in the Australian region, the red-necked wallaby has been introduced to parts of Great Britain. Feral populations breed on the island of Inchconnachan on Loch Lomond in Argyll and Bute, Scotland, and on the Isle of Man. Other colonies have existed in Devon, the Peak District, and the Ashdown Forest in East Sussex, and although these are now believed to be locally extinct, occasional sightings continue. Family: Macropodidae (kangaroos, wallabies, and kin)
 * Red-necked wallaby, Notamacropus rufogriseus introduced

Rodents
Order: Rodentia

Rodents are the largest order of mammals, comprising 40% of all species. They are characterised by a single pair of continuously growing incisors in each of the upper and lower jaws and are native to almost all major landmasses on Earth.

Family: Castoridae (beavers)
 * Eurasian beaver, Castor fiber globally,  in Great Britain, reintroduced

Lagomorphs
Order: Lagomorpha

The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas). Although 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 and hares)
 * European hare, Lepus europaeus introduced
 * Mountain hare, Lepus timidus
 * European rabbit, Oryctolagus cuniculus introduced

Eulipotyphlans
Order: Eulipotyphla

The order Eulipotyphla contains insectivorous mammals. Hedgehogs are easily recognised by their spines, while gymnures look more like large rats. Shrews and solenodons closely resemble mice, while moles are stout-bodied burrowers.

Family: Talpidae (moles)
 * European mole, Talpa europaea

Family: Soricidae (shrews)
 * Lesser white-toothed shrew, Crocidura suaveolens
 * Eurasian water shrew, Neomys fodiens

 * Eurasian pygmy shrew, Sorex minutus

Family: Erinaceidae (hedgehogs and moonrats)
 * European hedgehog, Erinaceus europaeus globally,  in Great Britain

Bats
Order: Chiroptera

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.

Family: Rhinolophidae (horseshoe bats)
 * Lesser horseshoe bat, Rhinolophus hipposideros
 * Greater horseshoe bat, Rhinolophus ferrumequinum

Family: Vespertilionidae (common bats, vesper bats, and kin)

Even-toed ungulates
Order: Artiodactyla

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. Cetaceans are also considered to be even-toed ungulates for phylogenetic reasons. Family: Suidae (pigs)
