''Callianassa subterranea'' is a species of burrowing ghost shrimp. This species is known by such generic common names as "mud shrimp" and "ghost shrimp". ==Description== ''Callianassa subterranea'' has an elongated body, a short small carapace, and a short rostrum. Its pale, translucent exoskeleton is not heavily calcified and remains relatively soft and flexible. Its large claws are unequal in size and are larger in males than in females. ''C. subterranea'' has very small eyes and grows up to in length.〔〔(【引用サイトリンク】publisher=UK Marine SACs Project )〕 Like many similar thalassinidean decapods, ''C. subterranea'' is a deposit-feeder that ingests sediment particles in order to scrape off and digest the organic coating called biofilm that sticks to them. To facilitate this type of foraging, its mouthparts, except for the mandible, are covered with a variety of setae designed for sediment denitrification. Its pereiopods are highly specialized for the digging activity of a deposit feeder and are not used for grooming.
