The common toadfish or common toado or toadfish or toado〔 (''Tetractenos hamiltoni'', formerly classified as ''Tetrodon hamiltoni''〔(World Register of Marine Species - Tetractenos hamiltoni (Richardson, 1846) ), accessed 8 March 2010.〕〔G.S. Hardy, "Revision of Australian species of ''Torquigener'' Whitley (Tetraodontiformes: Tetraodontidae), and two new generic names for Australian puffer fishes," ''Journal of the Royal Society of New Zealand'', Volume 13, No. 1/2, 1983, pp. 1–48. ()〕 or ''Torquigener hamiltoni'') is a species of fish in the Tetraodontidae family of order Tetraodontiformes, found along Australia's eastern coast, from northern Queensland to Flinders Island, and around Lord Howe Island,〔(Australian Faunal Directory: Tetractenos hamiltoni. )〕 as well as in New Zealand waters. It often buries itself in sand with only its eyes exposed.〔(Fishbase - Tetractenos hamiltoni ), accessed 8 March 2010 ((find mirrors )).〕 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.〔(Australian Museum: Common Toadfish. )〕 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.〔 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.〔(Ulrike E. Siebeck, Shaun P. Collin, Majid Ghoddusi, and N. Justin Marshall, "Occlusable corneas in toadfishes: light transmission, movement and ultrastruture of pigment during light- and dark-adaptation," ''Journal of Experimental Biology'', Volume 206, 2177-2190 (2003). )〕 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." As with other fish of this family, the flesh is poisonous, due to tetrodotoxin, and eating the fish can have fatal consequences.〔(Puffer fish poisoning: a potentially life-threatening condition ), accessed 8 March 2010.〕 ==See also== * Aquarium fishery * Smooth toadfish, ''Tetractenos glaber'' * List of brackish aquarium fish species 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Common toadfish」の詳細全文を読む スポンサード リンク
