The California two spot octopus posesses light sensitive proteins on its
skin, revealing that he can “see” with its skin. It doesn’t work the same as
eyesight but it has the ability to detect light. This is because the protein,
called opsin, that is found in eyes is in the octopus’ skin.
This octopus is considered one of the most
intelligent cephalopods and can carry out this ability without the command of
the nervous system. Its skin can detect an increase and a decrease in light,
meaning that its system works better at brightness than color change.
