Etymology:
Gymnothorax:
Greek, gymnos = naked + Greek, thorax, -akos = breast (Ref.

)
.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; reef-associated; depth range 5 - 100 m (Ref.
26165
). Tropical; 30°N - 26°S
Indo-Pacific: East Africa (Ref.
26165
) to the Galapagos, Cocos, and Clipperton islands; north to the Hawaiian and Ryukyu islands; south to Australia and the Kermadec Islands.

: 128 - 135. Greyish and speckled with irregular, dark markings (Ref.
3257
). Young yellowish with hollow-centered spots which becomes less conspicuous with age (Ref.
3257
). Lacks the molariform teeth as well as the depressible vomerine fangs present in most
Gymnothorax
and have two rows of vomerine teeth (Ref.
37816
).
Adults inhabit reef flats and rocky intertidal shorelines. Feed on small fishes and crustaceans, sometimes leaving the water in pursuit of prey (Ref.
9710
,
48635
). Benthic (Ref.
58302
). Simultaneous hermaphroditism is confirmed for this species (Ref.
103751
). Caught with various nets (Ref.
30573
). Solitary (Ref 90102).
