>For other uses, see Tiger (disambiguation). Tigers (Panthera tigris) are mammals of the Felidae family and one of four "big cats" in the Panthera genus. A group of tigers is called an "ambush" or a "streak". They are predatory carnivores and the largest of all living cats. Most tigers live in forests and grasslands (for which their camouflage is ideally suited). Among the big cats, only the tiger and jaguar are strong swimmers, and tigers are often found bathing in ponds, lakes and rivers. Tigers hunt alone and eat primarily medium-sized herbivores such as deer, wild pigs, and buffalo. However, they will also take larger or smaller prey on occasion. Humans are the tiger's only serious enemy and often kill tigers illegally for their fur or penises, which are used as aphrodisiacs in Chinese Medicine. Poaching for fur and destruction of habitat have greatly reduced tiger populations and it has been placed on the endangered species list. See more at Wikipedia.org...

[, also called sundown in some American English dialects, is the time at which the Sun disappears below the horizon in the west. It should not be confused with dusk, which is the (variously defined) point at which darkness falls, some time after the Sun itself sets (which begins twilight).The red hues of the sky at sunset are caused by the Rayleigh scattering of blue light by atmospheric dust. Relatively little red light is scattered in this way, and so the sky often takes on shades of red, orange and yellow. The color of a sunset may be enhanced by atmospheric phenomena such as clouds, smoke and smog produced by natural processes or human activity, and by ash from volcanic eruptions. A number of eruptions in recent times, such as those of Mount Pinatubo in 1991 and Krakatoa in 1883, have been sufficiently large to produce remarkable sunsets (and sunrises) all over the world.
