Range & Status
Prefers the vertical or overhanging surfaces of rocks in depths of 10-200m. Found on
the south and west coasts of Britain where it can be quite common in the appropriate
habitat. This species has suffered in the past as a result of over-collection by divers and by various types of demersal fishing. It is now protected under Schedule 5 of the Wildlife and Countryside Act (1981) against killing, injury, taking possession and sale. It is also on the UK list of Priority Species with its own Species Action Plan.
