How do squids change color? 🌈🦑 In the ocean’s twilight zone, glass squids like this one spotted by Nautilus Live rely on transparency to avoid predators, but when that fails, they activate backup camouflage. Tiny pigment sacs called chromatophores expand to darken their bodies and help them disappear into the deep-sea shadows. This remarkable ability to shift color isn’t just cool, it’s critical for survival in an open ocean with nowhere to hide. #Nautilus #Ocean #MarineBiology #Squid #Cephalo
