The giant squid's eyes are BIG. How big? As big as a human head. Bigger than any other eyes in the animal kingdom. Their size helps them gather the small amount of light that reaches the depths where giant squid live.
Squids are not birds. But they do have parrot-like beaks. Located at the center of its eight arms and powered by strong muscles, the giant squid's sharp beak can slice just about any kind of prey into bite-size chunks.
Scientists have never witnessed a scene like this. But giant squid sucker marks on the skin of sperm whales, and giant squid beaks in the whales' stomachs, provide evidence of underwater battles between these two marine giants.
