Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; depth range 80 - 3300 m (Ref. 127635), usually 350 - 800 m (Ref. 80214). Tropical, preferred 19°C (Ref. 107945)
Western Indian Ocean, Eastern Atlantic and the Mediterranean: Portugal to the Cape Verde Islands and the entire Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm 3.2 range ? - ? cm Max length : 22.0 cm TL male/unsexed; (Ref. 8); 7.1 cm CL (female); max. reported age: 6 years (Ref. 80242)
Demersal (Ref. 80214). Maximum length for females from Ref. 80234. Demersal on muddy bottoms of slopes of continental shelf, in zones close to submarine canyons. Moves from depths of 200 m during the night to 800 m during the day, and changes location within the year (Ref. 80214). Feeds on small benthic invertebrates mainly crustaceans and polychaetes and also carrion (Ref. 434).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
