Short description Identification keys | Morphology | Morphometrics

Anal soft rays: 12 - 14; Vertebrae: 33 - 34. Distinguished by having the following characters: length of internal ray of ventral fin very short, 15-30% of the long ray length; interorbital space wide and equal or slightly smaller than longitudinal eye diameter; palatine bones with teeth; fifth pore (pm5) of preoperculo-mandibular canal is usually paired; incomplete lateral canal with two to three autonomous segments at the end, with total number of pores from 13 + 2 + 2 + 2 to 23 + 2 + 2 (Ref. 93142).

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=0.00955 (0.00344 - 0.02648), b=3.09 (2.85 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 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 (10 of 100).
