These pandalid shrimp from top to bottom are the spot shrimp, Pandalus platyceros; the sidestripe shrimp, Pandalopsis dispar; the coonstriped shrimp, Pandalus hypsinotus; the northern shrimp, Pandalus borealis; and the humpy shrimp, Pandalus goniurus. The pandalid shrimp live mostly in the subtidal zone as adults; the northern shrimp lives as deep as 1,380 meters on soft mud bottom. The genus Pandalus has a boreo-artic distribution in the Pacific and Atlantic Oceans. In the Pacific, the species listed above generally range from the Bering Sea to California. These arthropods eat polychaetes, small crustaceans such as amphipods and euphausiids, limpets, and other shrimp. They are protandric hermaphrodites, which means they are first males, then become females.All pictured shrimp are commercially important.
