Cuttlefish are friendly creatures. They’ll check you out if you go diving with them and they are quite happy to let you accompany them on their hunt.
This video featured on this website wouldn’t exist without their friendly nature.
Cuttlefish have the most acute polarisation vision found in any animal. The eyes have a direct nervous link with its colour-changing skin cells.
Polarised light is invisible to humans. It is thought that cuttlefish are able to communicate through this covert channel.
Just like colour and intensity, polarisation is an aspect of light that can provide animals with information about the world around them.
