Etymology: Gymnothorax: Greek, gymnos = naked + Greek, thorax, -akos = breast (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 20 m (Ref. 90102). Tropical
Indo-West Pacific: East Africa to the Marshall Islands, north to the Ryukyu Islands, south to Australia. Likely to occur in Seychelles (Ref. 1623).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 44 - ? cm
Max length : 80.0 cm TL male/unsexed; (Ref. 1602)
soft rays: 0;
Vertebrae: 134 - 145. Chestnut brown species that becomes darker posteriorly. Differs from the uniformly brown G. pindae by lacking the fine serrations on the posterior edges of the lower jaw teeth and by having a mouth that may not quite close completely.
Inhabits relatively turbid areas of sheltered lagoon reefs (Ref. 1602, 37816). Including mangroves in 1-20 m (Ref 90102).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 29.3, mean 28.4 °C (based on 3191 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00048 (0.00026 - 0.00088), b=3.27 (3.12 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (57 of 100) .
