Etymology: Petroscirtes: Latin, petra, -ae = stone + Greek, skirteo = to jump.

पारिस्थितिकी
समुद्री प्रवाल-भित्ति संयुक्त; गहराई सीमा 1 - 10 m (Ref. 86942). Tropical; 25°N - 24°S

आकार / वज़न / Age
परिपक्व अवधि: Lm ? range ? - ? cm
Max length : 15.0 cm TL पुल्लिंग / अलिंग; (Ref. 9710)
पृष्ठीय रीढ़ (सम्पूर्ण) : 10 - 11; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 16 - 19; गुदा कांटा: 2; ऐनल सौफट रेज़: 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).
Body shape (shape guide): elongated.
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.
