Squids can change colors to match their surroundings thanks to pigment-filled cells called chromatophores. Researchers at Northeastern University discovered that these pigmentgranules can turn light into electricity.
When exposed to sunlight, the granules produce a charge. Biochemist Leila Deravi explained that the more granules there are, the more electricity they generate, which could potentially be used as a power source for the squid.
This amazing ability allows squids to quickly change their appearance underwater, where light levels are low. The researchers were impressed by how fast and accurate the color-changing process is.
By studying these light sensors in squids, scientists hope to improve technologies like wearable electronics. This discovery could lead to new advancements in various fields.
The research was published in the Journal of Materials Chemistry C. Squids, like the longfin inshore squid, use their color-changing skills to survive in the ocean by hiding from predators.
