Short description
Identification keys | Morphology | Morphometrics
Vertebrae: 191 - 194. This species of the Gymnothorax prolatus group is distinguished by the following characters: vertebrae in predorsal 6-7, preanal 83-91, total 191-194, preanal length 48.2-51.8% TL, maxillary teeth are biserial anteriorly and uniserial posteriorly, intermaxillary teeth uniserial (Ref. 129614).
Collected by bottom trawl with shallow demersal fishes, suggesting that the species lives at less
than 100 meters (Ref. 129614).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00048 (0.00025 - 0.00091), b=3.28 (3.12 - 3.44), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.9 ±0.6 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.
