Green Ormer

The Green Ormer (Haliotis tuberculata) is a common resident and culturally important species on Alderney. This marine mollusc is found from the lower shores of Alderney to depths of approximately 40 m, usually underneath rocks and boulders.

The shell of a Green Ormer is ear shaped with a row of several holes and an iridescent mother of pearl on the inside. Green Ormers feed on seaweeds and can grow up to 9 cm long.

Crazy about Crabs...

From the intertidal rocky-shores to the deep sublittoral reefs of Alderney's waters, crabs are in an amazing abundance. Anecdotally, Alderney hosts a variety of crab species, from small cryptic species such as the Hermit Crab (Pagurus bernhardus), to large, lumbering species, such as the Chancre/Brown Crab (Cancer pagurus).
