Morphology | Morphometrics
soft rays: 7 - 8. Black semicircular mark on each caudal lobe (Ref. 43281). Can be distinguished from its congeners by having a small scaleless midventral region only restricted to chest. Differs from P. robustus in having slightly crenulated rostral fold with 12-15 indentations on its distal margin, a shallower caudal peduncle (depth 63.7-71.3% of its length) and a larger mental adhesive disc (length 72.7-80.7% of its width) (Ref. 49783). Also Ref. 75600.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00317 - 0.01510), b=3.08 (2.90 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (25 of 100) .
