Recorded distribution in Britain and IrelandWidely distributed around the British Isles with sparse records along the east coast of England and west coast of Ireland.
Global distributionRecorded in the north east Atlantic from mid Norway southwards to the Spanish Sahara (West Africa), probably the whole of the Mediterranean.
HabitatInachus dorsettensis occurs in coastal waters from about 4 m to at least 300 m offshore on various substrates such as sand, muddy sand and seaweed-covered rocky beds.
- Chelipeds equal in size.
- Carapace triangular, and longer than broad.
- U-shaped cleft separating each half of the rostrum.
- Well developed spines ranging across the anterior part of the carapace.
Additional informationInachus dorsettensis covers itself in tiny pieces of sponge and sea weed to provide camouflage. It is often found living in the tentacles of the snakelocks anemone (see Ingle, 1996 for further details).
