Short description Morphology | Morphometrics

Vertebrae: 120 - 123. Dark purplish brown with small yellow spots which is sparse on the tail (Ref. 3257). This species is similar to Gymnothorax meleagris in having biserial maxillary teeth, with inner and outer series about equal in length; intermaxillary teeth arranged in a peripheral series, a median series, and an intermediate series on each side between the median and peripheral series. (Ref. 74922).

Benthic in crevices (Ref. 58302). Feeds on crustaceans and small fishes (Ref. 89972).

Estimates based on models

Preferred temperature (Ref. 115969): 21.5 - 28.4, mean 26.8 (based on 1927 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00065 (0.00043 - 0.00098), b=3.27 (3.15 - 3.39), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.67 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
