Short description Morphology | Morphometrics

Dorsal spines (total): 7 - 8; Dorsal soft rays (total): 12-13; Anal spines: 2; Anal soft rays: 11 - 12. Uniformly dark species that has smaller, but longer tubercles than C. maculatus and lacks a notch in the dorsal fin.

Biology     Glossary (e.g. epibenthic)

Found among branches of Stylophora mordax and certain Acropora corals (Ref. 9710). It never ventures outside the confines of the coral head where it swims between the branches foraging for other coral-dwelling types (Ref. 275). Anterolateral glandular groove with venom gland; at least in dorsal-fin spines (Ref. 57406).
