Open encyclopedia reference
The northern puffer, Sphoeroides maculatus, is a species in the family Tetraodontidae, or pufferfishes, found along the Atlantic coast of North America. Unlike many other pufferfish species, the flesh of the northern puffer is not poisonous, although its viscera can contain poison, and high concentrations of toxins have been observed in the skin of Floridian populations. They are commonly called sugar toads in the Chesapeake Bay region, where they are eaten as a delicacy. There was widespread consumption of northern puffers during the rationing that accompanied the Second World War, establishing a commercial fishery that reached its zenith in the 1960s. In much of the Northeast, the fish is known simply as "blowfish" or "chicken of the sea". They may also be sold as "sea squab".
