The polar tadpole group ( Cottunculus microps , syn .: C. konstantinovi, C. sadko ) is a species of fish from the family of the thick head bullhead (Psychrolutidae) living in the North Atlantic . It occurs from the southwestern Barents Sea over Svalbard and Bear Island , along the coast of Norway , near the Faroe Islands and Iceland , on the south and east coast of Greenland , near Labrador , in the Gulf of Saint Lawrence to New Jersey .
features
The tadpole group is a maximum of 30 cm long, the average size is 14 cm. Their skin is covered with spiky plates of bone and is therefore very rough. The large head is provided with four blunt bones that are located between and behind the eyes. The fish are gray and patterned with three to four dark vertical bands.
Way of life
The tadpole group lives on the sea floor at depths of 165 to 215 meters, and occasionally at depths of over 1300 meters. It feeds on poly bristles , hover shrimp , amphipods and woodlice spiders . The spawning season is probably in June and July. About 200 relatively large eggs with a diameter of 4.5 to 5.0 mm are laid.
