Animal Communication

Humboldt squid (Dosidicus gigas) can flash complex patterns of colour and light across their skin within milliseconds using chromatophores — pigment-filled sacs controlled by muscles. Research suggests these flashing patterns are a form of communication between individuals, potentially conveying information about prey, danger, or social status. Their skin also contains photoreceptors, meaning they may 'see' with their skin despite being colourblind in their eyes.

They produce infrasound calls, too low for human hearing, which travel through the earth and are detected by other elephants through their feet and bones. This allows them to communicate over vast distances, far beyond vocal range, to warn of predators or locate mates.
