Octopus 'look' with leather

Research by American scientists indicates that octopus skin is sensitive to light at the blue end of the spectrum.

Octopus skin feels the change of light

The University of California, Santa Barbara team, discovered similar proteins in the human eye at the skin of two octopus species, living off California. These proteins help the octopus feel light without the eyes or brain activity.

"Octopus skin does not sense the light as much as it does when using the brain and eyes. But it can sense the ever-changing light. It does not detect contrast and angles, but is aware " Brightness, " says UPI, says Desmond Ramirez, a member of the research team.

The scientists found that pigment cells swell and contract to respond to different light and the skin is most sensitive to light at the blue end of the spectrum.

All octopuses tend to disguise themselves thanks to pigments in the skin . Thanks to pigment cells , octopus can connect the ability to see from the eyes and brain.
