The Pufferfish is also known as the blowfish, fugu, swellfish, and globefish. It is called the pufferfish because when it is threatened, it puffs up to about twice its normal size by gulping water. In this engorged state, the pufferfish can swim at only about half its normal speed.

There are about 100 species of pufferfish. Most pufferfish are found in sub-tropical and tropical marine waters (including coral reefs) in the Atlantic, Pacific, and Indian Oceans. Some puffers live in brackish and fresh water. The scientific name refers to the four large teeth, fused into an upper and lower plate, which are used for crushing the shells of crustaceans and mollusks, their natural prey.
