Morfologie | Morfometrie
Dorsale stekels (totaal): 14 - 16; Dorsale zachte stralen (totaal): 9-11; Anale stekels 3; Anale zachte stralen: 8 - 10; Wervels: 30. Differs from P. marginatus and P. similis in having a group of enlarged pharyngeal teeth and from P. labridens in having a straight snout profile and a larger mouth, with the lower jaw one third or more of the head length.
Inhabits shallow vegetated inshore areas of the lake where it is commonly found around patches of Vallisneria. Feeds on invertebrates including the small gastropod, Gabiella stanleyi (Ref. 267).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 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).
Trofisch niveau (Ref.
69278): 3.4 ±0.52 se; based on food items.
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
