Description

The smooth trunkfish is a boxfish of the family Ostraciidae from the western Atlantic and Caribbean. The species grows to about 47 cm and has a triangular body armoured with bony plates that gives a rigid, box-like shape, dark with white spots. It lives solitarily or in small groups on coral reefs. With a jet of water ejected from its mouth it blows small bottom animals such as molluscs, crustaceans, worms, tunicates and sponges out of the sediment. When stressed the skin secretes a toxin. The species is marketed fresh locally.
