Écologie

Western Central Pacific: Moluccas, New Guinea, Solomon Islands; Belau and Yap in Micronesia.
Taille / Poids / Âge
Maturity: Lm ?  range ? - ? cm
Max length : 5.9 cm SL mâle / non sexé; (Ref. 1602)
Épines dorsales (Total): 10 - 11; Rayons mous dorsaux (Total): 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).
