UCSB Study Reveals Mechanism Behind Squids and Octopuses Ability to Change Color

Jul 25, 2013

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, the group of MCDB professor Dan Morse has delved deeper to uncover the mechanism responsible for the dramatic changes in color used by such creatures as squids and octopuses. The findings - published in the Proceedings of the National Academy of Science - are featured in the current issue of The Scientist.
