Ambushes prey, engulfing unwary crabs and small fish in broad mouth.
Despite name not venomous. Body brilliant silver with very dark patch close to gills. Rapid swimmer and usually shy, may occasionally approach divers with the sort of attitude that makes them grateful for their superior size. Often found in small groups where individual raising front dorsal fin may act as signal for all fish to swim off. 16 Unusual to get more than fleeting glimpse of this grey, torpedo-shaped fish.
