New Echinoderm-Crab Epibiotic Associations from the Coastal Barents Sea
During diving surveys for a Russian research project that monitored introduced species, red king crabs ( Paralithodes camtschaticus ) were collected at a coastal site of the Barents Sea to study the structure and dynamics of this species.
