Description

The longnose puffer is a pufferfish of the family Tetraodontidae from the eastern Pacific. The species grows to about 25 cm and has a stocky, light-brown body with dark spots and small skin lobes, and the beak-like jaw plates characteristic of puffers. It is commonly caught in bays, estuaries and shallow coastal areas. With its powerful beak it crushes hard-shelled prey such as molluscs, crabs and sea urchins. Like other puffers it can inflate itself, and its skin and organs can contain the poison tetrodotoxin; therefore do not eat this fish.
