Did you know?
The eyes of the Colossal Squid can be up to 11 inches in diameter, about the size of a soccer ball, making it the largest known eye in the animal kingdom. Those large eyes are useful in the dark waters where the squid lives, up to 1,000 meters below the surface of the ocean. The colossal squid not only has large eyes, but its pupils are also large, around 3.5 inches. A large pupil allows the eye to collect every last photon of light in the deep waters. A study showed that giant squids could detect a moving sperm whale from 394 feet with these eyes.
