Tetractenos
''Tetractenos'' is a genus of Tetraodontidae. The genus can be found throughout the Indo-West Pacific and Australia's southern and eastern coastlines. Species There are currently two recognized species in this genus: * ''Tetractenos glaber'' ( Fréminville, 1813) (Smooth toadfish) * ''Tetractenos hamiltoni'' ( J. Richardson, 1846) (Common toadfish) Description The general colour of the species in this genus varies, as at night they take on a deeper colour than during daytime, and, as with all toadfishes and puffers, the colour of skin changes slightly depending on the mood or stress level of the animal. For example, when a ''Tetractenos'' is in oxygen-depleted water, its underbelly will be a darker colour than the usual whitish-cream. The body of both species is covered in small, gravel-like pustules (spots). Small, sandpaper-like spines can be found on the body, and when the animal "puffs up" they stick out and make it feel even more rough. Although the colour varies, ''T. h ...

Smooth Toadfish
The smooth toadfish (''Tetractenos glaber'') is a species of fish 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 its close relative, the common toadfish (''T. hamiltonii''). The two are the only members of the genus ''Tetractenos'' after going through several taxonomic changes since discovery. Up to long with distinctive leopard-like dark markings on its dorsal side, the smooth toadfish has a rounded front and tapers to a narrow tail at the back. 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 sand and mud of the bottom sediment. Often an unwanted catch by anglers, the smooth toadf ...

Tetractenos Hamiltoni
The common toadfish (''Tetractenos hamiltoni''), also known as the common toado, toadfish or toado, (formerly classified as ''Tetrodon hamiltoni''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/ref> 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.Fishbase - Tetractenos hamiltoni accessed 8 March 2010 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetraodontidae
Tetraodontidae is a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowies, bubblefish, globefish, swellfish, toadfish, toadies, toadle, honey toads, Haaris Anwar fish, sugar toads, and sea squab. They are morphologically similar to the closely related porcupinefish, which have large external spines (unlike the thinner, hidden spines of the Tetraodontidae, which are only visible when the fish have puffed up). The scientific name refers to the four large teeth, fused into an upper and lower plate, which are used for crushing the hard shells of crustaceans and mollusks, their natural prey. The majority of pufferfish species are toxic and some are among the most poisonous vertebrates in the world. In certain species, the internal organs, such as the liver, and sometimes the skin, contain tetrodotoxin, and are highly toxic to most animals when ea ...

Tetraodontiformes
The Tetraodontiformes are an order of highly derived ray-finned fish, also called the Plectognathi. Sometimes these are classified as a suborder of the order Perciformes. The Tetraodontiformes are represented by 10 extant families and at least 349 species overall; most are marine and dwell in and around tropical coral reefs, but a few species are found in freshwater streams and estuaries. They have no close relatives, and descend from a line of coral-dwelling species that emerged around 80 million years ago. Description Various bizarre forms are included here, all radical departures from the streamlined body plan typical of most fishes. These forms range from nearly square or triangular (boxfishes), globose ( pufferfishes) to laterally compressed ( filefishes and triggerfishes). They range in size from '' Rudarius excelsus'' (a filefish), measuring just in length, to the ocean sunfish, the largest of all bony fishes at up to in length and weighing over 2 tonnes.

Chordate
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also Bilateral symmetry, bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit Metameric, metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cep ...

Sandpaper
upright=1.35, Sheets of sandpaper with different grit sizes (40 (coarse), 80, 150, 240, 600 (fine)). Sandpaper and glasspaper are names used for a type of coated abrasive that consists of sheets of paper or cloth with abrasive material glued to one face. There are many varieties of sandpaper, with variations in the paper or backing, the material used for the grit, grit size, and the bond. In the modern manufacture of these products, sand and glass have been replaced by other abrasives such as aluminium oxide or silicon carbide. It is common to use the name of the abrasive when describing the paper, e.g. "aluminium oxide paper", or "silicon carbide paper". Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, whether to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing).
