A slow swimmer

The pufferfish propels itself forward by moving its pectoral fins. It is a slow but precise method of locomotion, which is perfect when searching for prey among the cracks and stones.

A giant mouthful

The pufferfish is not a very good swimmer. So if a predator approaches, the pufferfish fills its stomach with water or air. This makes it big and round and almost impossible to swallow.

A dangerous meal

If a predator takes a bite out of a pufferfish, it will get a nasty surprise. The body of the pufferfish contains a deadly nerve toxin called tetrodotoxin, which causes paralysis and death.

A fishy beak

The teeth of the pufferfish are fused together, forming a kind of beak. With its strong jaws, the pufferfish can crush hard-shelled animals, like snails and mussels.

Freshwater pufferfish

The pufferfish is often associated with coral reefs, but of its 189 species, 30 live in fresh water. Millions of years ago, they migrated from the sea up rivers in South America, Southeast Asia and Africa.
