Common toadfish Information
( J. Richardson, 1846)
The common toadfish (Tetractenos hamiltoni), also known as the common toado, toadfish or toado,  (formerly classified as Tetrodon hamiltoni   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,  as well as in New Zealand waters. It often buries itself in sand with only its eyes exposed. 
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.  It has a maximum length of 14 cm.  It is similar in appearance to the smooth toadfish, but has smaller spots and more prominent spines in the skin.
