While octopus and cuttlefish are famous for their use of camouflage to match the color of the substrate, squid have never been reported displaying this ability. Now, in a study published in Scientific Reports, scientists from the Physics and Biology Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) have shown that squid can and will camouflage to match a substrate as a way of avoiding predators. This work opens up research avenues on how squid see and perceive the world around them. Furthermore, it sheds light on their behavior, and could thus inform conservation initiatives.
