They have a graviportal skeleton, with four stubby legs and four toes on each foot, supporting a portly frame. The
Fauna of Ireland Fauna of Ireland The fauna of Ireland comprises all the animal species inhabiting the island of Ireland and its surrounding waters. This table uses figures supplied by the National Parks and Wildlife Service. Only 26 land mammal species are native to Ireland, because it has been isolated from the European mainland (by rising sea levels after the Midlandian Ice Age), since about 14,000 BC. Some species, such as the red fox, European hedgehog, stoat, otter, pygmy shrew, and badger are common, whereas others, like the Irish hare, red deer, and pine marten are less common and generally seen only in
