zebra shell pattern material

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.

[he martial arts related meaning of Pattern see Tae Kwon Do and Kata (Karate).A pattern is a form, template, or model (or, more abstractly, a set of rules) which can be used to make or to generate things or parts of a thing, especially if the things that are generated have enough in common for the underlying pattern to be inferred or discerned, in which case the things are said to exhibit the pattern. Pattern matching is the act of checking for the presence of the constituents of a pattern. The detection of underlying patterns is called pattern recognition. See more at Wikipedia.org...]
