Marbled rock crab found on Guernsey

April 28th, 2009

A Marbled Rock Crab (Pachygrapsus marmoratus) was found on Guernsey’s west coast. This could be the first record of this species found on Guernsey. Pachygrapsus marmoratus has a shell or carapace of up to 3.6cm in length and is violet-brown to almost black in colour, with a marbled pattern of yellowish brown. The carapace is almost square in shape. The marbled rock crab is very fast moving and therefore difficult to catch.
