Description

The bullseye puffer is a pufferfish of the family Tetraodontidae reaching about 44 cm. The brown body bears on its back a pattern of concentric dark rings around a central spot, like a target - hence the name. The beak-like mouth consists of four fused tooth plates with which the fish crushes shellfish, crabs, snails and crustaceans. When threatened it pumps itself up with water into a ball. The species lives over sand and mud bottoms of coastal water and estuaries along the coast of Central and western South America and tolerates brackish water. Like other puffers its skin and organs may contain the deadly poison tetrodotoxin; it should not be casually eaten.
