Kurzbeschreibung Morphologie | Morphometrie

This species is distinguished in having smaller eyes (eyeball diameter 19-21.3% HL) and possessing fainter coloration with reduced lateral dark band as compared to its congeners; pectoral fin with 10 branched rays; weakly developed serrae in the posterior margin of the dorsal-fin spine (vs. well developed in P. laurentii); and, lacking the dorsal dark stripe along dorsal and anterior adipose fins (vs. presence in P. avanhandavae (Ref. 55501).

Collected mainly in soft-bottomed pools with very slow current, averaging 1.5 m deep, 5 m above the mainstream level. Individuals were observed calmly swimming near the bottom, in the midwater and near the surface. Elusive fishes and apparently photophobic (Ref. 55501).

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=0.00832 (0.00383 - 0.01808), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

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