Crambidae (grass moths)
- Scarce Crimson and Gold moth, Pyrausta sanguinalis, a small distinctively marked moth, dark yellow with crimson bands across the forewings merging with crimson edging.

Here, it is only found along the northern coast at The Ayres National Nature Reserve, where its larvae live in silken tubes and feed on the flowers of wild thyme growing in the former sand pits. At The Ayres adults fly during the day mostly in June but have been recorded in July and into early August. The species was once more widespread in Britain but has declined in recent years and is thought to be extinct in its former range in north-west England and Scotland.[8]

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.[24]
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 disappearing 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.
