Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 80; Anal soft rays: 52; Vertebrae: 62. This species is distinguished from its congener T. disjunctus, by the following characters: pectoral fin peduncle much longer than its width (vs. equal in length); precaudal vertebrae 22 (vs. 16); total vertebrae 62 (vs. 52); long rakers on first gill arch 14 (vs. 6); horizontal eye diameter 3.1% SL (vs. 1.3% SL); interorbital width 0.8% SL (vs. 3.3% SL); no posterior mandibular pore (vs. present); anterior infraorbital pores 1 (vs. 3); opercular spine not covered by skin (vs. covered by skin); otolith height to thickness 2.5 (vs. 1.8); in alcohol head and body light brown (vs. dark brown) (Ref. 93598).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
