Liocarcinus marmoreus, sometimes known as the marbled swimming crab, is a species of crab found in the northern Atlantic Ocean and North Sea.[3] It may be found on sand and gravel in the sublittoral and lower littoral zones,[4] down to a depth of 84 metres (276 ft),[5] from the Azores and the Alboran Sea (the westernmost section of the Mediterranean Sea) as far north as the Shetland Islands.[2] It reaches a carapace length of 35 millimetres (1.4 in),[5] and is distinguished from other similar species by the presence of three similarly-sized teeth on the edge of the carapace, between the eyes, and by the marbled colouration on the carapace.[3] L. marmoreus is sometimes parasitised by the barnacle Sacculina.[4]
