Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 16; Dorsal soft rays (total): 8; Anal spines: 3; Anal soft rays: 5. Body creamy tan with prominent dark brown band crossing the body from notch in dorsal fin to base of anal fin spines; depth 32-34% SL. Head moderately sized 37-39% SL. Eyes 27-30% HL. Mouth small, horizontal. Lateral line nearly straight. Caudal fin rays 12. Compared to
C. australis, the species have a deeper interorbit and occipital pit; a smaller and rounder mouth; and, a narrow chevron-shaped brown band at caudal fin base (Ref. 33839).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Occurs in estuaries (Ref. 75154).
