deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 3; duri punggung lunak (Keseluruhan (total)) : 12 - 14; Duri dubur: 0; Sirip dubur lunak: 8 - 9; vertebrata, bertulang belakang: 19. Branchiostegal rays: 6 (Ref. 36491).
Adults inhabit rocky areas, including the intertidal zone. Found on sandy and muddy bottoms (Ref. 9269). Young individuals feed heavily on crustaceans but as they grow bigger, they consume more and more fish, sometimes catching and eating fishes their own size (Ref. 4930).
