Overview
Main identification features
  • white + dense black spots
Dorsal and anal fins covered with skin, but clearly evident; dorsal fin origin above level of gill opening; posterior nostrils not tubular, at most a raised rim; teeth pointed and well developed, but not of canine proportions; teeth in upper jaw in a single row, conical at front of jaw, becoming compressed along side of jaw; a single conical tooth between the top jaws; two rows of teeth at front of lower jaw, the outer row small; no depressible fangs at middle of upper jaw; rear of roof of mouth with 2 rows of teeth.

White with dense covering of small black spots; juveniles with relatively larger black spots in about three longitudinal rows.

Size: to 140 cm.

Habitat: rocky bottoms.

Depth: 0-5 m.

Widespread in the tropical Indo-Pacific from East Africa to the Americas; in the eastern Pacific it occurs at western Panama and Costa Rica and offshore islands including Clipperton, the Revillagigedos, Cocos and the Galapagos.

Bohlke and Randall (2000) reassinged this species from Siderea to Gymnothorax.

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines : 0; Anal soft rays : 0; Vertebrae : 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 ).

Biology     Glossary (e.g. epibenthic)

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).
