Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 13.0 cm TL mâle / non sexé; (Ref. 9710)
Épines dorsales (Total) : 7; Rayons mous dorsaux (Total) : 25 - 29; Épines anales: 1; Rayons mous anaux: 24 - 27; Vertèbres: 26 - 27. Pale to bluish gray in color; pectoral fin base with a narrow, pale blue-edged, black band; postorbital head with irregular, pale to iridescent blue bands and spots. Chin with a median, fleshy protuberance narrowing to a thin fold. Scales embedded, close-set, non imbricate (except on posterior part). 1st dorsal fin lower than 2nd; 2nd dorsal and anal fins elevated anteriorly. Closely resembles P. heteropterus but lacks the blue mark on the tail (Ref. 1602).
Body shape (shape guide): elongated; Cross section: compressed.
Adults inhabit lagoon and seaward reefs, over rubble and sand bottoms (Ref. 9710). They are found from shallow silty estuaries and inlets to outer reef lagoons to about 10 meters depth, but may also be seen deep on coastal slopes to 25 meters depth (Ref. 48637). They occur in pairs occupying the same burrow, but at times more than 2 individuals will retreat to the same refuge (particularly true for juveniles). Monogamous (Ref. 52884). Adults feed on zooplanktons (Ref. 89972).
