The body of the pufferfish is short and plump. Pufferfish are born with very thin, small spines. The tough, thick skin of the pufferfish was once used to make helmets. The teeth in the upper and lower jaws of the pufferfish are joined together as if they were a sharp blade. This allows the pufferfish to easily chew through the shells of hard corals. Most pufferfish are tropical marine fish, with only a few species living in freshwater. Once threatened, the pufferfish swallows water or air to inflate its body into a spiny ball, making it difficult for natural predators to get a bite. The internal organs of many species of pufferfish contain a deadly neurotoxin. The toxicity of tetrodotoxin has been measured. Its toxicity is equivalent to 1,250 times that of the highly toxic drug sodium q chemical, and it only takes 0.48 milligrams to kill a person. In fact, the muscles of the pufferfish do not contain the toxin. The most toxic parts of the puffer fish are the ovaries and liver, followed by the kidneys, blood, eyes, gills and skin. The toxicity level of the puffer fish is also related to its reproductive cycle. Pufferfish carrying eggs in late spring and early summer are the most toxic. The toxin can cause nerve paralysis, vomiting, chills in the limbs and then cardiac and respiratory arrest.
