Distribution and Habitat
Distribution in Britain & Ireland	Recorded distribution is limited to the south coast of Britain, west coast of Scotland and a single site in the Kenmare River area, in southern Ireland. However, Callianassa subterranea is likely to be more widespread than records suggest.
Global distribution	The species has a geographical distribution from the Mediterranean Sea to the coast of Norway.
Biogeographic range	Not researched	Depth range	0 - 20 m
Migratory	Non-migratory / Resident
Distribution Additional Information	Callianassa subterranea is likely to be more widespread than records of adults suggest. Many observations of the deep-burrowing habit of the species indicate that the adults will usually be unavailable to conventional benthic sampling equipment (Atkinson & Nash, 1990) because of the depth of the shrimps burrows. Burrows in mud are relatively simple and deep (30-81cm) compared to those in sandier sediments which tend to be shallow and complex (Rowden & Jones, 1997). These differences may be related to the associated food content of the substratum.
