Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 5; Raggi dorsali molli (totale) : 17 - 21; Spine anali: 0; Raggi anali molli: 17 - 21; Vertebre: 32 - 33. Post-pelagic are almost fully transparent and more slender compared to those established in the benthic phase. Variable in color from black to red and yellow, usually in a mix of bands and spots (Ref. 48635). Total body number of plates 31-35. Caudal fin truncate, rounded or lanceolate. Caudal fins of females modified into brood pouch (Ref. 9829).
Body shape (shape guide): other; Cross section: flattened.
Adults usually settle along reef edges in current-prone areas (Ref. 48635). Uncommon species found solitary or paired, among branches of gorgonians, floating weeds, or crinoids (Ref. 9710). They feed mostly on mysids but also target small benthic shrimps (Ref. 48635). Females carry the eggs in their pelvic fins that are modified to form a brood pouch (Ref. 205).
