Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 3; Raios dorsais (total) : 12 - 14; Espinhos anais: 0; Raios anais : 8 - 9; Vértebras: 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).
