Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 16 - 17; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9 - 11; गुदा कांटा: 3; ऐनल सौफट रेज़: 9 - 10; जानवरों की रीड़ का जोड़: 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.
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).
