Marine wildlife

Sea birds

Important breeding densities of fulmar, shag, peregrine, kittiwake, gulls, guillemot, razorbill, chough and raven are found along the cliffs and rocky coast around the Chasms, Calf of Man, Bradda Head and Fleshwick and guillemots and razorbills form rafts on the sea. Gannets are frequently seen diving offshore for food between March and October.


Seals gather in large groups on rocks around the Calf and Kitterland to rest, breed and give birth. They are more sensitive to disturbance between September and November during their breeding season, especially when they have young.

Basking sharks

Every summer, from May until September the Isle of Man is a hotspot for basking sharks. Keep a look out for basking sharks all around the Island. You may see their huge dorsal fin but they often swim just below the surface too. If one is visible, others may be close by.

Porpoises, dolphins and whales

Porpoises can be seen all year round and are more sensitive to disturbance in the summer months when they have young. Risso’s dolphins are sighted along the east coast in spring and the south coast in autumn, often in groups. Bottlenose dolphins are less common but groups of 200 individuals have been seen.

Minke whales are sighted along the east coast in autumn and along the west coast in summer. They grow up to 10 metres in length and occasionally jump clear of the water so keep your distance. Other species of whales and dolphins are also seen around the coast.

Safe bathing and no wake zones/harbour areas
