Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 14 - 16; членистые (мягкие) лучи спинного плавника (общее число) : 9 - 11; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 8 - 10; позвонки: 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.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), 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.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
