Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 1 - 100 m, usually 5 - 50 m (Ref. 37816). Tropical; 35°N - 32°S, 72°E - 171°E
Indo-West Pacific: Maldives and India to Papua New Guinea, north to southern Japan, south to Lord Howe Island (Ref. 9710).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 16 - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 2272)
Dorsal spines (total): 8; Dorsal soft rays (total): 13 - 16; Anal spines: 2; Anal soft rays: 12 - 13. Body compressed, its width 3.3-4 in depth (Ref. 37816). Normally yellow, but sometimes nearly all black and juveniles take-on colors of the local venomous Meiacanthus blennies that are yellow or grey (Ref. 48635).
Found mainly in coastal habitats in semi-silty conditions (Ref. 48635); also found near caves and crevices in rocky and coral reefs from a few meters to at least 100 m. A predator that feeds on surprisingly large prey, swallowed whole through its expandable jaws (Ref. 48635). Feeds mainly on fishes. Secretes the skin toxin grammistin under stress (Ref. 2334).
