Regularly seen species

Harbour porpoise, Phocoena phocoena (Perkin/perkyn chadjin)^[6]
Bottlenose dolphin, Tursiops truncates (Lheimmeyder mooar-tronnagh)^[7]
Common dolphin, Delphinus delphis (Doraid/Lheimmeyder cadjin giare-ghobbagh)^[8]
Risso's dolphin, Grampus griseus (Lheimmeyder marrey garroo)^[9]
Minke whale, Balaenoptera acutorostrata (Muc-varrey ny maaigyn bane)^[10]

Rarely seen species

Humpback whale, Megaptera novaeangliae^[11]
Killer whale, Orcinus orca^[11]
Fin whale, Balaenoptera physalus^[11]

Vagrant species

Sei whale, Balaenoptera borealis – a single adult was stranded on Langness in May 1925. Its skeleton is on display in the Natural History Gallery of the Manx Museum ^[12]
Long-finned pilot whale, Globicephala melas – no known records in Manx waters, but have been sighted in the Irish Sea^[13]
Striped dolphin, Stenella coeruleoalba - on 20 December 2017 a single striped dolphin beached and died in Castletown harbour and was preserved for display within the Manx Museum^[14]

Extinct populations

Grey whale, Eschrichtius robustus – a coastal whale probably once found in the Irish Sea, however the species' North Atlantic population was extirpated in the 18th century.^[15]

Domestic animals

All sorts of domesticated species have been brought to the Isle of Man by humans over the millennia. Two notable landrace breeds have evolved distinctively on the island:

Manx cat, a domestic cat (Felis catus) with genetic abbreviation of the tail, which may range from no tail at all to essentially full-size. Developed as a standardised breed in the late 19th century, the Manx cat has become a popular breed worldwide, but is in danger of diseappearing on the island itself, as it is being out-bred by other cats imported over the last century by primarily English immigrants. The long-haired variety is called the Cymric cat in some breed registries, and was primarily developed in Canada, not the Isle of Man.
Manx Loaghtan, a variety of domestic sheep (Ovis aries) with brown wool and four horns, rare outside the island and considered "at risk" by the Rare Breeds Survival Trust. The dwindling numbers of the sheep have also caused a local decline in the population of wild corvid birds called choughs – the sheep keep grasses short, making the insect prey of the birds easier to find, and the sheep dung attracts beetles preferred by the birds.
