Most pufferfish are found in sub-tropical and tropical marine waters (including coral reefs) in the Atlantic, Pacific, and Indian Oceans. Puffer fish may also live in brackish and fresh water. Puffer fish are carnivores who eat sponges, sea urchins, corals and small crustaceans. They crush and grind their prey with their heavy, fused teeth. Puffer fish range in size from just a few inches to almost 2 feet long. A few species have spines on their body, and may be referred to as porcupine fish, but many do not. Their skin is very elastic. Many parts of their body is poisonous and contains tetrodoxin. Even so, they are a delicacy in Japan and many skilled chefs prepare pufferfish (called fugu) as a delicacy.
