Short description
Identification keys | Morphology | Morphometrics
A species of Meiacanthus (subgenus Meiacanthus) with major portion of dentary gland dorsally positioned and held in place laterally by dorsolateral flange of dentary; dorsal fin IV, 25 or 26; color pattern characterized by a single black mid-lateral stripe that is bluntly rounded at its terminus on the caudal-fin base; dorsal fin pale distally with a wide black proximal stripe; white or yellow stripe above and below dark mid-lateral stripe; belly and flanks pale to rich yellow (Ref. 87904).
Body shape (shape guide): fusiform / normal.
Adults inhabit sheltered bays, along mangrove and rocky shores (Ref. 90102). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
