The smooth toadfish (Tetractenos glaber) is a species in the pufferfish family Tetraodontidae. It is native to shallow coastal and estuarine waters of southeastern Australia, where it is widespread and abundant. French naturalist Christophe-Paulin de La Poix de Fréminville described the species in 1813, though early records confused it with what is now the only other member of its genus, the common toadfish (T. hamiltonii). Up to 16 cm (6 1⁄4 in) long with distinctive leopard-like dark markings on its upperparts, the smooth toadfish has a flattened belly and an elongate body tapering to a slender tail. Its back and fins are rounded. Unlike most of its relatives, it does not have prominent spines on its body. Like other pufferfish, it can inflate itself with water or air. It forages for its preferred foods—molluscs and crustaceans—in sandy or muddy sediment. Often an unwanted catch by anglers, the smooth toadfish's flesh contains the poison tetrodotoxin, and eating it may result in death.
