Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i ryggfenan (totalt) : 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).
