The Northern puffer (Sphoeroides maculatus) is a saltwater fish of the family Tetraodontidae that grows up to 36 cm.
Description
The northern puffer is a stocky fish of the family Tetraodontidae (pufferfishes) reaching about 36 cm. The brown, spotted body has a white belly with small skin prickles and a parrot-like beak of fused teeth. When threatened the fish gulps water or air and inflates into a spiny ball, too large for most predators. The species lives on sandy and weedy bottoms of shallow coastal water and bays along the east coast of North America. With its beak it crushes shellfish, molluscs, sea urchins and worms. The organs and skin of pufferfishes can contain highly toxic tetrodotoxin; only the back muscle, when expertly prepared, is eaten.
