Description
The threetooth puffer is a rare, primitive pufferfish and the only species of the family Triodontidae from the Indo-West Pacific. The species reaches about 54 cm and owes its name to the three tooth plates in the mouth. Its most striking feature is a large, expandable belly flap with a black eye-spot: by spreading this flap the fish suddenly appears much larger, deterring predators. It lives in deeper water over reefs, from about 50 to 300 m, and feeds on bottom invertebrates such as molluscs and crustaceans. The species is rarely seen.
