Seven Deadly Colours (book review)

Title :- Seven Deadly Colours.

By :- Andrew Parker

Published :- Free Press, Great Britton 2005 Paperback (270 pages).

Outline :- Eyes can vary slightly, and thus some animals can see infrared with different structures to their retina cones. Some butterflies have structured wing development at such a fine scale that light passes through at a set refractive indices, and thus the reflected light can be seen across a valley. Glow worms and other phosphorescent animals produce light in a variety of chemical interactions, even when there is no sunlight to begin with. Black and white banded snakes move at such a selected curved speed so as to appear green to the eye, and thus achieve camouflage. The science of biology is used by animals to achieve camouflage, display themselves for mating, or see pray, and it reflects the many mechanisms that exploit the basic colours.
