Ecologie
marien demersaal; diepte 1 - 5 m (Ref. 90102). Tropical; 10°N - 12°S
Western Central Pacific: Moluccas, New Guinea, Solomon Islands; Belau and Yap in Micronesia.
Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 5.9 cm SL mannelijk / geslacht onbekend; (Ref. 1602)
Dorsale stekels (totaal): 10 - 11; Dorsale zachte stralen (totaal): 16-18. Closely related to P. variabilis, but is usually more elongate and has a bulbous or elongate snout.
Adults inhabit weedy areas such as Sargassum beds. They occur in shallow seagrass beds where they hide by pressing itself against a blade of seagrass. 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).
