背棘 (總數) : 16 - 17; 背的軟條 (總數) : 9 - 11; 臀棘: 3; 臀鰭軟條: 9 - 10; 脊椎骨: 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.
外部列的強烈地標示的縱向側面的斑紋與三尖齒區隔 P. triaenodon 和所有的其他種的本屬。 顏色圖案在標本中是特別地特殊的。
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).
曾經捕捉沙質底部之上.(參考文獻 5595) 時常採自了在 10-15 公尺的特別拖網但是已經被發現於 35 公尺.(參考文獻 267)
