deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 16 - 17; duri punggung lunak (Keseluruhan (total)) : 9 - 11; Duri dubur: 3; Sirip dubur lunak: 9 - 10; vertebrata, bertulang belakang: 31. The strongly marked longitudinal lateral stripes and the tricuspid teeth of the outer rows separate P. triaenodon from all other species of the genus. The color pattern is particularly distinctive in the specimens.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Has been caught over sandy bottoms (Ref. 5595). Frequently taken in ad hoc trawl hauls at 10-15 m but has been found at 35 m (Ref. 267).
