The largest eyes of any animal belong to the giant squid. The eyes of a giant squid can approach 1 foot in diameter, which is about the size of a human head or a dinner plate.

The giant squid's enormous eyes help it see in the darkness of the deep sea. These elusive creatures have been talked about for centuries, but scientists know very little about them because their isolated underwater habitats make them hard to research. In addition to its large eyes, the giant squid also has a tough, sharp beak that helps it kill and eat its prey.
