Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 16 - 17; Rückenflossenweichstrahlen (insgesamt) : 9 - 11; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 9 - 10; Wirbelzahl: 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 based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), 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

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Preiskategorie (Ref. 80766): Unknown.
