Description
The buffalo trunkfish is a boxfish (Ostraciidae) from the western Atlantic Ocean. The species grows to about 45 cm and has a body enclosed in a stiff, bony armour of fused plates, with two horn-like projections above the eyes. It inhabits seagrass beds, coral rubble and seaward reefs to about 50 m deep. It feeds on various small benthic invertebrates such as molluscs, crustaceans, worms and sessile animals. When stressed it can release a toxic substance (ostracitoxin) to deter predators. The species is harmless to humans.
