Scientists attached a video camera to Humboldt squid in order to observe how they use their color-changing skin cells in the wild.
Analysis of the footage revealed that the squid repeatedly flash red in the presence of other Humboldt squid, possibly as a way of communicating — though what, scientists aren’t yet sure. When close to the surface, the squids’ chromatophores flicker, giving their skin a hue of sunlight shining through the water column — possibly as a form of camouflage.
