The Zebra is a part of the horse family, Equidae, native to central and southern Africa. They are most well known for their distinctive black and white stripes.

Zebras are either white with black stripes, or black with white stripes. These stripes are typically vertical on the head, neck, forequarters, and main body, with horizontal stripes at the rear and on the legs of the animal. The zebra crossing is named after the zebra's white on black stripes.

Zoologists believe that the stripes act as a camouflage mechanism. This is accomplished in several ways. First, the vertical striping helps the zebra hide in grass. While seeming absurd at first glance considering that grass is neither white nor black, it is very effective against the zebra's main predator, the lion, which is color blind. A zebra standing still in tall grass may not be noticed at all by a lion and as zebras are herd animals the stripes help in camouflage is by confusing the lion — a number of zebras standing or moving close together may appear as one large animal, making it more difficult for the lion to pick out any single zebra to attack. A herd of zebras scattering to avoid a predator will also represent to that predator a confused mass of vertical stripes travelling in multiple directions making it difficult for the predator to track an individual visually as it separates from its herdmates.

Stripes are also believed to play a role in social interactions, with slight variations of the pattern allowing the animals to distinguish between individuals.

A more recent theory, supported by experiment, posits that the disruptive coloration is also an effective means of confusing the visual system of the blood-sucking tsetse fly.[

Alternative theories include that the stripes coincide with fat patterning beneath the skin, serving as a thermoregulatory mechanism for the zebra, and that wounds sustained disrupt the striping pattern to clearly indicate the fitness of the animal to potential mates.

African bushmen of Guinea refer to these stripes in their native Madango as "sukuku" which means "lightning" and plays an important role in the customs of the eastern region of Kankan. In ancient beliefs it was thought zebras were sent by the spirit of lightning and rain to remind people that time changes, good seasons of abundant fertility might turn out to be droughts, that giving life may take another's life away, that black can't exist without white.


Species


There are four extant species, as well as several subspecies. Zebra populations vary a great deal, and the relationships between and the taxonomic status of several of the subspecies are well known.

The Plains Zebra (Equus quagga, formerly Equus burchelli) is the most common, and has or had about twelve subspecies distributed across much of southern and eastern Africa. It, or particular subspecies of it, have also been known as the Common Zebra, the Dauw, Burchell's Zebra (actually the subspecies Equus quagga burchelli), and the Quagga (another extinct subspecies, Equus quagga quagga).

The Mountain Zebra (Equus zebra) of southwest Africa tends to have a sleek coat with a white belly and narrower stripes than the Plains Zebra. It has two subspecies and is classified as endangered.

Grevy's Zebra (Equus grevyi) is the largest type, with an erect mane, and a long, narrow head making it appear rather mule-like. It is an inhabitant of the semi-arid grasslands of Ethiopia, Somalia, and northern Kenya. The Grevy's Zebra is one of the rarest species of zebra around today, and is classified as endangered.

Although zebra species may have overlapping ranges, they do not interbreed. This held true even when the Quagga and Burchell's race of Plains Zebra shared the same area. According to Dorcas McClintock in "A Natural History Of Zebras," Grevy's zebra has 46 chromosomes; plains zebras have 44 chromosomes and mountain zebras have 32 chromosomes. In captivity, Plains Zebras have been crossed with mountain zebras. The hybrid foals lacked a dewlap and resembled the Plains Zebra apart from their larger ears and their hindquarters pattern. Attempts to breed a Grevy's zebra stallion to Mountain Zebra mares resulted in a high rate of miscariage.


By the way it is zebras and not zebra's. Usually people of Indian Origin make that or such mistakes ( No offence Meant )

By the way, zebras can mate with horses. I saw the result of such a mating once: a foal with dark stripes.
