The Puffer fish is also known as the blowfish, fugu, swellfish, and globefish. They are called puffer fish because when it feel threatened it puffs up two times its actual size by gulping water.
There are around 100 different varieties of puffer fish and they are found in coral reefs in the India, Pacific and Atlantic Oceans. Many puffer fish can be found in fresh water as well. Some puffer fish swim to freshwater and some live their entire life in fresh water, without ever going to the sea. Most puffer fish are found in sub-tropical and tropical marine waters along the coast lines.
The puffer fish has a powerful
toxin in its liver and ovary called tetrodotoxin. This toxin harms
humans when they eat puffer fish. The Japanese have a special way of
cooking and cutting the puffer fish so the toxins do not harm them
when eating puffer fish.
