![Stripes
It was previously believed that zebras were white animals with black stripes, since some zebras have white underbellies. Embryological evidence, however, shows that the animal’s background color is black and the white stripes and bellies are additions.[3]

The 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 black and white stripes.
A wide variety of hypotheses have been proposed to account for the evolution of the striking stripes of zebras. The more traditional of these (1 & 2, below) relate to camouflage.
1. The vertical striping may help the zebra hide in grass. While seeming absurd at first glance, considering that grass is neither white nor black, it is supposed to be effective against the zebra’s main predator, the lion, which is color blind[dubious – discuss]. In addition, even at moderate distances, the striking striping merges to an apparent grey.
2. Another hypothesis is that since zebras are herd animals, the stripes may help to confuse predators—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.[8][unreliable source?]
3. It has been suggested that the stripes serve as visual cues and identification.[3] Although each striping pattern is unique to each individual, it is not known whether zebras can recognize one another by their stripes.
4. One theory suggested by an innovative experiment posits that the disruptive colouration is an effective means of confusing the visual system of the blood-sucking tsetse fly.[9]
5. Alternative theories include that the stripes coincide with fat patterning beneath the skin, serving as a thermo-regulatory mechanism for the zebra, or that wounds sustained disrupt the striping pattern to clearly indicate the fitness of the animal to potential mates.
