Triodon macropterus, also known as the threetooth puffer, is a tetraodontiform fish, the only living species in the genus Triodon and family Triodontidae.[1] Other members of the family are known from fossils stretching back to the Eocene.[2]

It is native to the Indo-Pacific, where found at depths to 300 m (980 ft).[3] Its name comes from the Greek tria meaning "three" and odous meaning "tooth", and refers to the three fused teeth making up a beak-like structure.

The threetooth puffer reaches a maximum length of 54 cm (21 in).[3] It has a distinctive shape, with a huge belly flap as large as or larger than its body; it inflates this with seawater when threatened. The flap bears an eye-spot, and is inflated by rotating the shaft-like pelvis downwards. This makes the animal appear much larger to predators, and less likely to be eaten.[2]

The threetooth puffer is also known as the Black-spot keeled pufferfish, and was first scientifically described by Lesson in 1831.[4]
