$10 Uneetee: Camouflage

0 pennies earned

Alright, so Daniel Gilbert made a funny with his zebra camouflaged by a bar-code t-shirt...and we like it; but we can't let this unnecessary zebra-hate continue without knowing the facts. Thank you almighty Wikipedia, for sharing with us some substantiated theories unencumbered by restrictive copyright issues:

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 supposed to be effective against the zebra's main predator, the lion, which is color blind.

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.

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.
