Overview
Pandalus borealis, the northern prawn, or cold-water prawn (also known as pink or deep-water shrimp in North America), are crustaceans belonging to the family Pandalidae. The species has a wide distribution throughout the North Atlantic and North Pacific Oceans (the Pacific form is generally regarded as a subspecies, Pandalus borealiseous). The species occurs as far south as the North Sea, Massachusetts, Oregon and Japan. Northern shrimp are hermaphroditic. They develop initially as males, then become female after around 3 years, and complete their lives as females. Life span is around 5 years, although possibly up to 8 years in northern latitudes. They spawn in autumn and females carry the eggs until April/May, when they hatch and the pelagic larvae are released. Total adult length is about 15 cm. This species inhabits areas of soft, muddy sediment with a depth range from 20-1300 m. Prawns migrate vertically at night to feed on zooplankton. Northern prawn are heavily predated on by fish and marine mammals.
