Description

The prickly toadfish is a puffer (Tetraodontidae) from the temperate coastal waters of Australia. The species has a stocky, pear-shaped body with a short tail and a skin covered with small spinelets. It is usually observed in estuaries to about 20 m deep and is nocturnal. As an omnivore it nibbles on small benthic invertebrates. Like other puffers it can inflate itself with water and its tissue contains the deadly poison tetrodotoxin; never eat this fish.
