The giant squid is massive and when full grown can be at least 33 feet (10 meters) long. These mysterious eight-armed creatures are rarely seen by humans. Most of what we know about them comes from finding them washed up on beaches. The largest of these hard-to-find giants ever found measured 59 feet (18 meters) in length and weighed nearly a ton (900 kilograms).
More recently, in 2004 researchers in Japan took the first images ever of a live giant squid. And in late 2006, scientists with Japan's National Science Museum caught and brought to the surface a live 24-foot (7-meter) female giant squid.
Giant squid, along with their cousin, the colossal squid, have beach ball size eyes! Their eyes are the largest eyes in the animal kingdom and are about 10 inches (25 centimeters) in diameter. Their big eyes help them see better underwater! They are able to spy objects in dark depths where most other animals would see nothing.
