The octopus seems to have the ability to see just about everywhere at once.

Now thanks to the results of a new study published in the Journal of Experimental Biology however these remarkable cephalopods have been found to possess yet another unique feature to help set them apart from the rest of the ocean's wildlife - their skin contains the same pigment proteins that can be found in eyes.What this means is that the octopus can literally sense light through its skin, an advantage that enables it to see its surroundings and camouflage its appearance accordingly.

To change color the octopus possesses a unique mechanism which uses thousands of special cells called chromatophores found just beneath the surface of its skin.

Perhaps most impressive of all however is the fact that it can do all this while color blind.
