Summary

Description

The body of this crab is often covered by an encrusting sponge, but is recognised by its distinctive pink pincers and the very small fourth and fifth legs. The carapace is oval, up to 5 cm long, 6.5 cm broad with three small teeth between the eyes and five strong ones on each side. The body and legs are covered with hairs giving the crab a furry appearance.

Recorded distribution in Britain and Ireland

Recorded from South West of England, the eastern English Channel, the Channel Islands, Lundy, Skomer and north Pembrokeshire, Cardigan Bay, Bardsey Island and the Llyn Peninsula.
