Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 14 - 16; Raios dorsais moles (total) : 9 - 11; Espinhos anais: 3; Raios anais moles: 8 - 10; Vértebras: 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).
