Vision is the most important sense for many animals to observe and scan their surroundings.

The squid has the highest-evolved eyes in all of the animal kingdom. Its pupils, shaped like a "W," cannot distinguish colors, but can see the polarization of lights. This animal is thus able to judge the distance even in the dark. The squid can change the shape of its eyes to better observe its surroundings. A "built-in" sensor helps it catch prey both in front of it and behind its back.
