Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 12; Raios dorsais (total) : 19 - 20; Espinhos anais: 2; Raios anais : 17 - 18. Nasal and supraorbital cirri slender and pointed, nuchal cirrus shot and simple. Both sexes with low occipital crest. Breast and anterior part of dorsal fin with characteristic markings; breast with brownish-yellow spot; anterior dorsal fin with red spot. Anterior anal rays in males somewhat elongate. Attains 5 cm SL.
Facultative air-breathing (Ref. 126274); Adults occur in coral reefs (Ref. 559); common in the intertidal zone (Ref. 637). 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).
