Short description Morfología | Morfometría

Espinas dorsales (total): 2; Radios blandos dorsales (total): 6; Radios blandos anales: 11 - 13; Vértebra: 43. Distinguished by the following combination of characters: small dots irregularly placed (forming 8-9 rows) and most developed in the anterior two thirds of body; the mouth with thick striated lips; an enlarged posterior branch of the dorsal premaxillary process synchondrally articulated with the lateroanterior margin of mesethmoid; a right-angled posterolateral margin of mesethmoid; the exposed centra of the 7th vertebrae; and a large pharyngobranchial 3 with a well developed dorsal crest. Differs from P. fur in possessing more gill rakers on the first arch (19-22 vs. 16-18) and a wider mouth (32.0-35.1% HL vs. 24.6--30); and from P. absconditus in having a larger interorbital distance (22.2-29.2% HL vs. 18.6-22.7), a relatively smaller ratio between orbital diameter and interorbital width (70.8-115.0 vs. 104.1-148.9); a shallower body (19.0-24.5% SL vs. 21.6-26.9), a shorter head (25.8-28.9% SL vs. 27.5-30.8), a smaller predorsal length (36.2-39.9% SL vs. 38.7-42.9) and a smaller prepelvic length (47.4-51.0% SL vs. 49.3-53.1). Vomerine tooth plates occasionally develop in P. heroldi while they are always present in P. absconditus and absent in P. fur (Ref. 41259).

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=0.00646 (0.00383 - 0.01090), b=3.11 (2.97 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.3   ±0.6 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100).
