List of mammals of Great Britain

This is a list of mammals of Great Britain.
The Great Britain mammal fauna is impoverished compared with that of continental Europe. This is because there was only a short time between the last ice age and the flooding of the land bridge between Britain and the rest of Europe. The list only has land species which crossed before the creation of the English Channel, and those later brought in by humans.
Native (indigenous) species have three possible definitions:
a species which 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.
Rodentia
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 continuously and must be kept short by gnawing. Most rodents are small though the coypu (once introduced to Great Britain, but subsequently eradicated) can weigh up to 9 kg (15.5 lb).

Lagomorpha
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.

Hedgehogs
Superorder: Laurasiatheria
Order: Erinaceomorpha
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.
European hedgehog Erinaceus europaeus
Shrews and moles
Superorder: Laurasiatheria
Order: Soricomorpha
The "shrew-forms" are insectivorous mammals. The shrews and soledons closely resemble mice while the moles are stout-bodied burrowers.

Bats
Superorder: Laurasiatheria

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.

Even-toed ungulates
Superorder: Laurasiatheria
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.

Odd-toed ungulates
Superorder: Laurasiatheria
Order: Perissodactyla
The odd-toed ungulates are browsing and grazing mammals. They are usually large to very large, and have relatively simple stomachs and a large middle toe.
Feral horse Equus ferus caballus - Exmoor pony, Dartmoor pony
Carnivora
Superorder: Laurasiatheria

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.
