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.
Across the Channel Islands, several environmental groups record and tag Green Ormers, with the aim to investigate their movements and population structures. If you find a tagged Green Ormer, please email Dr Mel Broadhurst-Allen via email@example.com
