More on author: Valenciennes.

Issue
Original description based on drawings included in an unpublished manuscript by Vandelli; Capello (1870:64, pl. 7) redescribed and figured the holotype (unique specimen acquired in 1786 by Ferreira sent to Lisbon from Barcelos and studied by Vandelli), precised its historic and geographic origin, and discussed the species; new combination by Regan (1904:261); no recent work.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01514 (0.00712 - 0.03216), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).

Pseudacanthicus histrix (Valenciennes, 1840)
