Bony tubercles well developed on head and body. Usually there are 3 distinct rows of large tubercles laterally, with much smaller tubercles scattered between the rows.  Colour variable, usually bluish-grey, yellow-green or yellow-brown.

    Geographical Distribution

    Launch the Aquatic Species Distribution map viewer

    Throughout the north of 45º N latitude (Portugal and southern Bay of Biscay) in appropriate habitats to Spitsbergen, including Iceland. Elsewhere, know from western Greenland, Hudson Bay, and the coasts of North America as far south as Maryland.
    Habitat and Biology
    Benthic on rocky bottomsusually between 50 and 150 m, but occasionally to 400 m;may occur in floating seaweed; basically solitary rather than a schooling fish.Feeding more intensive in the winter; favoured are ctenophores, medusae, small crustaceans, polychaetes worms and small fishes.
    Move inshore to spawn, in summer in waters of about 8º C; may have up to about 300,000 eggs, 2.2-2.7 mm in diameter, in masses of 15,000-100,000; male guards eggs-mass aggressively. 
    Size
    Maximum males 50 cm, females 61 cm; weight to 9,5 kg, but ussually much smaller.
    Interest to Fisheries
    Valued for their eggs, which make an inexpensive caviar. The total catch reported for this species to FAO for 1999 was 9 822 t. The countries with the largest catches were Iceland (3 373 t) and Greenland (3 057 t).
