Length at first maturity / Size / Weight / Age
Maturity: Lm 21.0, range 18 - ? cm
Max length : 39.0 cm TL male/unsexed; (Ref. 27437); max. published weight: 630.00 g (Ref. 40637); max. reported age: 54 years (Ref. 55701)
soft rays: 6. Head spines strong - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). 2nd anal fin spine long; body slender (Ref. 27437). Pinkish yellow in color, with 3 or 4 horizontal green stripes on body, light ventrally; green streaks on caudal fin membranes (Ref. 27437).
A common inhabitant of both inshore and offshore areas (Ref. 2850, 6885). Found on rocky as well as soft bottoms (Ref. 2850). Viviparous (Ref. 34817).
