Pufferfishes or puffers are members of the Tetraodontidae family. They are found in tropical and subtropical areas of Atlantic, Indian and Pacific oceans. Their jaws are modified to form a beak of 2 pairs of heavy and powerful teeth. They have the ability to inflate themselves with either air or water as a deterrent to predators. The viscera, skin, and blood of most species are poisonous. Some species have the ability to excrete poison from their skin and some even have poisonous flesh.
Pufferfishes occur most frequently in shallow inshore waters, sometimes entering brackish and fresh waters. They are often found alone and seems to eat anything.
There are 26 genera and about 190 species of pufferfishes worldwide. About 32 species are found in Malaysia waters.
