Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 1; Anal soft rays: 70 - 79; Vertebrae: 57 - 59. Pectoral fin length 14.0-16.9% SL; pectoral spine length 9.0-11.0% SL; eye diameter 20.0-23.9% HL; vomerine teeth present in two closely-situated elliptical patches; a distinct nuchal concavity; and mandibular barbels reaching beyond anterior base of anal fin. Pectoral spine and articulated segments sexually dimorphic in mature individuals. Male with spine broad and somewhat flattened dorsoventrally, with 10-12 distinct posterior serrations; proximal articulated segments with 9-18 well-developed posterior serrations. Females with spine slender, with 12-14 smaller posterior serrations; proximal articulated segments with 6-9 small and poorly-developed posterior serrations. Fins hyaline, with small dark-brown spots occasionally present (Ref. 42937).

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=0.00562 (0.00279 - 0.01132), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.7 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).
