The common toadfish (Tetractenos hamiltoni), also known as the common toado, toadfish or toado,[2] (formerly classified as Tetrodon hamiltoni[3][4] or Torquigener hamiltoni) is a species of fish in the family Tetraodontidae of order Tetraodontiformes, found along Australia's eastern coast, from northern Queensland to Flinders Island, and around Lord Howe Island,[2] as well as in New Zealand waters. It often buries itself in sand with only its eyes exposed.[5]
The fish is sandy to whitish in colour, with small brown spots over most of the back and upper sides, and brown bars and blotches beneath.[6] It has a maximum length of 14 centimetres (5.5 in).[5] It is similar in appearance to the smooth toadfish, but has smaller spots and more prominent spines in the skin.[6]
Like some other fish, the common toadfish is able to vary the amount of pigment in its cornea, which becomes yellow in colour under bright light.[7]
It is (rarely) used as an aquarium fish for brackish-water aquariums. Along with related toadfish species, it is known in Australia as a "toadie."[citation needed]
As with other fish of this family, the flesh is poisonous, due to tetrodotoxin, and eating the fish can have fatal consequences.[8]
