Length at first maturity / Size / Weight / Age
Maturity: Lm 1.0, range 1 - 1 cm Max length : 16.0 cm TL male/unsexed; (Ref. 8); 18.6 cm (female); common length : 14.0 cm TL male/unsexed; (Ref. 8); common length :16 cm TL (female); max. reported age: 3.00 years (Ref. 80253)
Demersal (Ref. 85316). Maximum depth range from Ref. 114857; minimum common depth from Ref. 80253. Prefers mud or muddy sand substrates (Ref. 8). Juveniles settle at around 100 m, though can be detected up to 300 m, while larger individuals are always found deeper than 350 m (Ref. 80253). Feeds on benthic organisms (clams, mysids and small crangonids; Ref. 434). Also occurs in pelagic depths between 100 to 200 m (Ref. 92299). Opportunistic predator (Ref. 112170).
The species has a life cycle of 2 to 3 years (Ref. 80253). Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833).
