A group of unusual fishes famous for their ability to inflate their body by swallowing air or water. Their scales are modified into very small, stiff and short spines, which are evident when the fish is inflated. Their jaws are powerful and their teeth are fused, resembling a parrot's beak. With these, they are able to crush small snails and crustaceans. Pufferfishes have a circumtropical distribution, and most are marine or euryhaline.
Euryhaline; 20 cm; oviparous; carnivorous; usually solitary; pelagic. Indigenous, fairly common. Canals, mangrove creeks and river mouths, usually in brackish water.
Better, but incorrectly known as Tetraodon or Arothron fluviatilis, this attractive puffer is commonly seen in aquaria, where it is often acclimatised to freshwater. The Spotted Pufferfish, like many others in the family, is poisonous, and may cause death when eaten.
