For hundreds of year, people have heard reports of monsters that rise out of the sea to attack ship. Many people now think these "monster" were probably giant squid. Giant squid share many of the same characteristic as other squid. But they are much larger-up to 13 meter (43 feet) in length. They also have the larger eyes of any animal in the world. This helps them catch deep-sea fish. Their only predator are some kind of whales. When it is attacked, the giant squid has a very clever means of getting away. It shoots dark ink into the water, the whale can't see, so the squid has a chance to swim away. For years, scientists were unable to catch a giant squid on film. but they did find squid body parts in the stomachs of whales. The scientists were able to use these to figure out how big the squid was. The first photo of a live giant squid were taken in 2004. It is definitely as monsters as people believed!
