Environment / Climate / Range
Benthic; depth range 0 - 600 m (Ref. 78657). Temperate, preferred 11°C (Ref. 107945); 85°N - 45°N, 110°W - 40°E
Arctic, Northern Atlantic and the Mediterranean: Canadian Arctic Archipelago and the Atlantic Ocean. Temperate to polar climates.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 5 - 7.2 cm Max length : 10.2 cm SHL male/unsexed; (Ref. 360); common length : 5.1 cm SHL male/unsexed; (Ref. 360)
Maximum depth from Ref. 106864. Common in the continental shelf (Ref. 106864). Common in the subtidal to 200 m depth in the northern Atlantic (Ref. 78657). Usually found on hard bottoms (Ref. 95730), as well as soft bottoms from 5 to 600 m (Ref. 106864). Also found to occur in areas with sludge (Ref. 96352). Relatively sedentary (Ref. 106864). It is a necrophagous, scavenger species (Ref. 96498). Feeds on polychaetes, molluscs, echinoderms and other smaller crustaceans (Ref. 106864). Females gather in groups to deposit eggs in a communal mass of egg capsules where veligers develop and metamorphose inside and later hatch out as young individuals (Ref. 360).

Harms, J. 1993. (Ref. 2711)
