Description

The naked puffer is a pufferfish of the family Tetraodontidae from the eastern Pacific. The species grows to about 35 cm and has a stocky body with a smooth, nearly spineless skin and the beak-like fused jaw plates characteristic of puffers. Adults live in bays and over sandy bottoms; juveniles often in more open water. With its powerful beak it crushes hard-shelled prey such as molluscs and crustaceans. Like other puffers it can inflate itself, and its skin and organs can contain the poison tetrodotoxin; therefore do not eat this fish.
