Etymology: Chirolophis: Greek, cheir = hand + Greek, lophos = crest (Ref. 45335). More on author: Walbaum.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 10 - 400 m (Ref. 58426), usually 10 - 30 m (Ref. 35388). Temperate; 0°C - ; 72°N - 49°N, 70°W - 32°E
Northeast Atlantic: Norwegian coast to Finmarken and Waranger Fjord, occasionally Murman coast, rare in Skagerrak, Kattegat and Öresund, around Helgoland, also British Isles; also the Orkneys, Faroes, Shetlands and Iceland (Ref. 4782). Northwest Atlantic: Canada (Ref. 7251).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm SL male/unsexed; (Ref. 4782); 18.0 cm TL (female); common length : 17.5 cm SL male/unsexed; (Ref. 4782)
(total): 50 - 54;
soft rays: 35 - 40. Snout blunt; mouth frog-like. With a large fringed tentacle above each eye, a smaller one in front and others on top of head and on the anterior dorsal fin spines. First anal fin ray a short flexible spine. Lateral line represented by a dorsal and a mediolateral branch of neuromasts (the former begins as a short canal, with 4-5 pores.
Usually over rocks and among seaweeds, never in intertidal zone, at 20 m, but descends from 100-280 m (Ref. 4782). Benthic (Ref. 58426). Feeds on bottom invertebrates (small mollusks, polychaetes, hydroids, sponges), also algae (Ref. 4782). Spawns in October - December (Ref. 35388).
