A large male of 44mm carapace width was found dead and decaying inside an old lobster creel that had at some point been caught in a trawl and brought back to shore. Specimen found at Newlyn Marina, Newlyn, Cornwall. 21.11.20.

This species is found at depths beyond 80m (R.W. Ingle, Synopses of the British Fauna Shallow-water Crabs) and to ca 2800 m (Guerao & Abelló, 1999), from Marlin.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
