| Puffers have round bodies that are capable of inflating into a balloon-like shape by the intake of air or water. The probable purpose of inflation is to prevent themselves from being swallowed by predators. They also have 4 strong teeth in their jaws which form a beak, and they usually have small fleshy tabs (lappets) or spiny prickles on parts of their bodies. They are a marine species but may occasionally enter freshwater. Although the flesh is considered a delicacy in many countries, the puffers produce a deadly toxin called tetrodotoxin that, although concentrated in the organs, can contaminate the flesh and cause lethal poisoning if consumed. |
