Short description
Morfologia | Morfometria
Spine dorsali (totale): 14 - 16; Raggi dorsali molli (totale): 9-11; Spine anali 3; Raggi anali molli: 8 - 10; Vertebre: 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
Phylogenetic diversity index (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).
Trophic level (Ref.
69278): 3.4 ±0.52 se; based on food items.
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
