Mechanism behind squids' and octopuses' ability to change color revealed

[unable to retrieve full-text content]Color in living organisms can be formed two ways: Pigmentation or anatomical structure. Structural colors arise from the physical interaction of light with biological nanostructures. A wide range of organisms possess this ability, but the biological mechanisms underlying the process have been poorly understood. Now researchers have delved deeper to uncover the mechanism responsible for the dramatic changes in color used by such creatures as squids and octopuses.
