Dungeness crab live in intertidal to epipelagic zones along the Pacific coast from Aleutian Islands to Point Conception and are occasionally found in Baja Mexico. Adults are opportunistic carnivores that will bury into the sand, while larvae primarily feed on zooplankton and phytoplankton. In recent years, populations have been declining due to habitat degradation and overfishing, but have also been impacted by sea otter predation.
