Length at first maturity / Size / Peso / Age
Maturity: Lm ?, range 16 - ? cm
Max length : 25.0 cm TL maschio/sesso non determinato; (Ref. 2272)
Spine dorsali (totale): 8; Raggi dorsali molli (totale): 13-16; Spine anali 2; Raggi anali molli: 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).
