zebra wiki:
ga">Equus quagga Equus grevyi *See Equus for other species. Zebras are members of the horse family native to central and southern Africa. All have vividly contrasting black and white vertical stripes (hence the zebra crossing named after it) on the forequarters, often tending towards the horizontal at the rear of the animal. Originally, most zoologists assumed that the stripes acted as a camouflage mechanism, while others believed them 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 an effective means of confusing the visual system of the blood-sucking tsetse fly.

>For alternative meanings, see ear (disambiguation). An ear is an organ used by an animal to detect sound waves. The term may refer to the entire system responsible for collection and early processing of sound (the beginning of the auditory system), or merely the externally-visible part. Not all animals have ears in the same part of the body.
