Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 16 - 17; Radios blandos dorsales (total) : 9 - 11; Espinas anales: 3; Radios blandos anales: 9 - 10; Vértebra: 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).
