Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; non-migratory; depth range 1 - 67 m (Ref. 90102). Tropical; 32°N - 26°S
Indo-Pacific: East Africa to the Tuamoto Islands, north to southern Japan, south to New Caledonia and French Polynesia; including Marianas and Marshalls.
Length at first maturity / Size / Weight / Age
Maturity: Lm 107.0, range 94 - 120 cm
Max length : 130 cm TL male/unsexed; (Ref. 2334)
Dorsal spines (total): 0; Anal spines: 0; Vertebrae: 270 - 286. Has three fleshy tentacles on the tip of its lower jaw, a single fleshy pointed projection at the tip of its snout, and tubular anterior nostrils ending in gaudy, fanlike expansions.
Adults occur in lagoon and seaward reefs. They are secretive species normally hidden in sand or rubble, sometimes with only its head protruding. Feed on small fishes (Ref. 9710, 48635, 75154, 89972). Juveniles all black, males have yellow dorsal fin and females change to a nearly all yellow color, but usually with blue in the posterior (Ref. 48635). Only moray that undergoes abrupt changes in coloration and sex: it is a protandrous hermaphrodite, i.e., functioning males reverse sex to become females. Protandry is diagnosed based on colouration, but not confirmed (Ref. 103751).
