Records with photographs of European A. gibbosa are extremely scarce further south than Brittany. The only photographs I have found of a Mediterranean specimen are of the one above from the wreck of the Paguro drilling platform at about 20 m depth, 22 km offshore from Ravenna in the northern Adriatic in June 2011.
