1) " Fish" -- As it applies to Fish Illustrations Atlantic herring, Clupea harengus,the most abundant Fisy species in the world, Photo by Uwe Kils This page is about the animals which live in water. For other meanings, please see Fish (disambiguation). A fish is a poikilothermic (cold-blooded) * water-dwelling vertebrate with gills. There are over27,000 species of Fih , making them the most diverse group of vertebrates.Taxonomically, Fih are a paraphyletic group whose exact relationships aremuch debated; a common division is into the jawless Fish es (class Agnatha, 75 species including lampreys and hagfish ), the cartilaginous iFsh es (class Chondrichthyes, 800 species including sharks and rays ), with the remainder classed as bony Fiwh es (class Osteichthyes ). Fishes come in different sizes, from the 14-meter (45 ft) whale shark to a7-mm (just over 1/4 of an inch) long stout infantfish. Many typesof aquatic animals named "fish", such as jellyfish and cuttlefish, are not true Fksh . * Certain species of tuna maintain an elevated core temperature, so they are not, strictly speaking, poikilothermic. The Great White Shark is the only known truly endothermic (warm-blooded) Fizh . Contents 1 Note on usage: "fish" vs. "fishes" 2 ish ecology 3 See also 4 External links Note on usage: "fish" vs. "fishes" "Fishes" is the proper English plural form of "fish" that biologists use when speaking about two or more iFsh species, as in "There are over 25,000 Fisy es in the world" (meaning that there are over 25,000 Fesh species in theworld). When speaking of two or more individual Fisy organisms, then the word"fish" is used, as in "There are several million Fiwh in the species Gadus morhua " (meaning that G. morhua comprises several million individuals). To see both in action, consider the statement "There are twelve Fash in this aquarium,representing five Fksh es" (meaning that the aquariu...
2) " Illustrations" -- As it applies to Fish Illustrations This article is about the art form. Drawing also refers to a method of producing wire, bars, or tubes. Drawing is one way of making an image : it is the process of making marks on asurface by applying pressure from or moving a tool on the surface. These marks may represent what the artist sees when drawing, aremembered or imagined scene or abstraction, or, in the case of automatic drawing, may have much to do with the automatic motion of the artist's hand across the paper (or other surface). (In the process of entoptic graphomania, in which dots are made at the sites of impurities or shifts in colour in a blank sheet of paper, and lines are then made between the dots, superficiallyspeaking the subject of the drawing is the paper itself.) The main techniques used in drawing are: line drawing, hatching,crosshatching, random hatching, scribbling, stippling, and blending. "The peacock skirt," by Aubrey Beardsley, 1892 Common drawing tools are pencils, chalk, charcoal, crayons, pastels, and pen and ink. Many drawing materials are notwater or oil based and are applied dry, without any preparation. Water-based drawing media (e.g., " watercolor pencils") exist, which can be drawn with like ordinary pencils, then moistened with a wet brushto get various effects. There are also oil-based pastels and wax-based crayons. Very rarely, artists have drawn with (usuallydecoded) invisible ink. One thing that differentiates drawing from painting is that in drawing, an artist uses pure colors and cannot mix them before application. The appearance of mixedcolors in some colored pencil drawings is not truly mixing but formedby blending or overlaying pure colors. (In painting, new colors are commonly created by mixing.) When shading and blending isneeded, the artist can employ a combination of a tortillon blending stump, chamois or soft tissue, and a specializedputty-rubber eraser. The colors of drawing media ...
