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.

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.
