Max length : 60.0 cm TL maschio/sesso non determinato; (Ref. 26550); peso massimo pubblicato: 900.00 g (Ref. 40637); Età massima riportata: 20 anni (Ref. 56049)
Usually found on sand or mud bottom near rocks and eelgrass, from the coast to a depth of 60 m. A secretive species, it feeds on small fishes and benthic crustaceans during the day (Ref. 9342). Capable of tolerating ample fluctuations of temperature (from 7.5 to 32°C) and survive extreme cold intervals (Ref. 9342). Pelagic spawners (Ref. 56049). Important game fish caught in bays and harbors (Ref. 9342). Minimum depth range based on occurrence (Ref. 79604).
Pelagic spawner (Ref. 56049). Protogyny (Ref. 32126) as proposed has been corrected by a more detailed study on several species which confirmed this species and all of the members of the genus to be gonochoristic (Ref. 103751).
