Description

The sharpnose puffer is a small tobyfish (Tetraodontidae) from reef water of the Indian Ocean. The species grows to about 7 cm and has a stocky, scaleless body with a pointed snout and a brown to olive pattern of spots and lines; when threatened it inflates with water. With a strong beak-like jaw it gnaws at invertebrates, coral and algae. Its organs contain deadly tetrodotoxin; the fish must not be eaten.
