Pufferfishes and Porcupinefishes are closely related and share the ability to inflate their bodies by gulping water into a highly distensible sac that opens off the lower part of the stomach. If this is not enough to deter predators, these fishes are also highly toxic.

There are 120 species worldwide of which 70 occur around Australia. The small Sharpnose Puffers range from 8-20 cm long but the largest species is the Starry Puffer (Arothron Stellatus) that can grow to 1 m in length.
