Description

The grass puffer is a small pufferfish of the north-western Pacific. It grows to about 16 cm and has a stocky body with a green-brown back dotted with small pale spots and a white belly; instead of separate teeth it has a beak of fused teeth. The species lives demersally in coastal waters and tidal zones. It eats crustaceans, molluscs, worms and algae. It is known for mass spawning: at spring tide adults swim ashore in large numbers to spawn in the sand. The flesh contains tetrodotoxin and is poisonous; the species can inflate itself in defence.
