Short description
সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স
পৃষ্ঠীয় কাঁটা (মোট ) : 9; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 28 - 32; পায়ূ কাঁটা : 3; পায়ূর নরম পাখনা্তুন্ড: 20 - 22. This species can be distinguished from its congeners by the following set of characters: D IX, 28-32 (mode 29); A III, 20-22 (mode 21); a single ocellated spot on soft-rayed portion of dorsal fin; absence of ocellated spot on anal fin; band on caudal peduncle usually orange when fresh (obscured in preserved specimens) with a short, saddle-like, blackish dorsal streak; a sharply pointed pelvic fin with an nearly straight posterior contour when spread (most obviously in large specimens >10 cm SL); presence of dark band on each interopercle joining on ventral midline with anterior margins forming a sharply pointed "V" in ventral view (Ref. 128188).
Most specimens were obtained using trawls from depths greater than 34 m; while juveniles occur in shallow coastal waters in that region. Since no differences in dentition were apparent between C. chrysozonus, which feed on sponge tissue and benthic invertebrates, and C. calendula, it is likely that both have a similar dietary habit (Ref. 128188).
