Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 2683); common length : 40.0 cm TL male/unsexed; (Ref. 2683)
Inhabits various types of bottoms on the continental shelf and upper slope, down to at least 200 m, older individuals occurring at greater depths. Feeds mainly on fish, and to a lesser extent, on tunicates and mollusks (Ref. 3688). Minimum depth from Ref. 58018.
