🎥 + 💭: matthewunderwater “How can they change colors before our eyes? Cuttlefish are colorblind, yet they can change the color of their bodies with full control. Their skin has three layers of cells, pigment sacs that expand and contract, reflective cells that bend light, and a base layer that boosts contrast. Millions of cells, controlled in real time. How they know what colors to produce is still not fully understood. The leading theory is that their W-shaped pupils detect color through focus rather than receptors. Unlike anything else in nature. Research has shown that cuttlefish can solve puzzles, delay gratification, and remember past events. They've been around for millions of years and we're just now trying to figure them out.“ #MarineMonday #Cuttlefish
