Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 7 - 10; Mjukstrålar i ryggfenan (totalt) : 17 - 23; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 12 - 17. Yellowish with brown spots, most numerous on back; narrow stripes on soft dorsal, pectoral and caudal fins, with dark spots on fin rays (Ref. 4698). Head height equal to head width. Males with a long pointed genital papilla (Ref. 35388).

Biologi     Ordlista (t.ex. epibenthic)

Found on muddy, sandy or rocky bottoms or among algae (Ref. 4698). Maximum depth at 930 m (Ref. 58426). Benthic (Ref. 58426). Feeds on benthic polychaetes, crustaceans (Hyppolyte, Boreophausia), and large hyperiids (Phascolosoma) (Ref. 4698). Males usually below 7 cm and females below 12 cm. Lives at temperatures -1.7-10°C. Female lays 150-1,000 eggs with a diameter of 3mm (Ref. 35388).
