deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 15 - 17; duri punggung lunak (Keseluruhan (total)) : 8 - 9; Duri dubur: 3; Sirip dubur lunak: 4 - 5. Head spines very strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronal spines absent; large head and elongate body; strong spiny ridge on head; 3rd dorsal spine not much longer than 2nd, 4th or 5th; strong notch on pectoral fin (Ref. 27437). Bright red with some black on fins; gill chamber mostly pale (Ref. 27437). Caudal slightly rounded (Ref. 6885).
Body shape (shape guide): fusiform / normal.
Very common on soft bottoms (Ref. 2850). Oviparous (Ref. 205). Eggs are extruded in floating gelatinous masses (Ref. 31279). Have a thick glandular tissue on posterior margin of fin spines which is believed to be venomous (Ref. 57406). Rarely taken by game fishers (Ref. 27436). Flesh sweeter than that of other rockfishes (Ref. 27436).
Unlike other representatives of this group, this species has internal fertilization Oviparous (Ref. 6885). Females possess specialized ovarian structures including stalk-like ovigerous lamellae and secretory epithelia (Ref. 32832).
