Morphology | Morphometrics
Dorsal
spines

Anal
spines: 3;
Anal
soft rays: 9 - 10;
Vertebrae: 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).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00709 - 0.03231), b=2.97 (2.80 - 3.14), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.3 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (17 of 100) .
