With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers at the University of California, Irvine have drawn inspiration from this natural wonder to develop a technological platform with similar capabilities for use in a variety of fields, including the military, medicine, robotics and sustainable energy. … "We are fascinated by the mechanisms underpinning the blue-ringed octopus' ability to rapidly switch its skin markings between hidden and exposed states," said senior co-author Alon Gorodetsky, UCI professor of chemical and biomolecular engineering.
