Concealing Coloration
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the bioluminescence, ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of Active ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower Flounder In Kona May 2010
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants (Flowering plant, angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: Sepal, calyx, modified leaves; Petal, corolla, the petals; Stamen, androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing Style (botany), style and Stigma (botany), stigma, which receives the pollen at the tip of the style, and Ovary (botany), ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterospory, heterosporous, and so can produce gamete, sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between ...
