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

The shifting colors of bigfin reef squid aren’t just mesmerizing, they’re a sophisticated form of communication and camouflage, powered by pigment cells called chromatophores. By studying how these squids change color, we gain insight into how marine species interact with each other and adapt to their environments. Every observation turns exploration into understanding and understanding into the knowledge we need to protect the ocean and the life it sustains. | OceanX
