Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 15.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 9710)
Ραχιαίες άκανθες (συνολικά): 10 - 11; Μαλακές ραχιαίες ακτίνες (συνολικά): 16-19; Εδρικές άκανθες 2; Μαλακές εδρικές ακτίνες: 16 - 19. Sexually dimorphic: males are orange-brown while females are sea-green dorsally and lighter below. Similar to P. breviceps in shape but has a blotched, rather than lined pattern on the body. Some color form are probably habitat related. The plain form is mainly green and has numerous tiny pearly spots and occurs in seagrass beds (Ref. 48636).
Adults occur in seagrass beds of shallow lagoons. Also in Sargassum rafts during or immediately after wet season (Ref. 48636). Replaced by P. thepassi at Solomon Islands (Ref. 90102). They feed primarily on small crustaceans and occasionally on scales from fishes. 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). This form was named by Bleeker (1852) as Petroscirtes bankanensis.
