Giant squid, along with their cousin, the colossal squid, have the largest eyes in the animal kingdom, measuring some 10 inches in diameter. These massive organs allow them to detect objects in the lightless depths where most other animals would see nothing.
Like other squid species, they have eight arms and two longer feeding tentacles that help them bring food to their beak-like mouths. Their diet likely consists of fish, shrimp, and other squid, and some suggest they might even attack and eat small whales.
They maneuver their massive bodies with fins that seem diminutive for their size. They use their funnel as a propulsion system, drawing water into the mantle, or main part of the body, and forcing it out the back.
Scientists don't know enough about these beasts to say for sure what their range is, but giant squid carcasses have been found in all of the world's oceans.
