Giant squid can snatch prey up to 33 feet (10 meters) away by shooting out their two feeding tentacles, which are tipped with hundreds of powerful sharp-toothed suckers. These feeding tentacles are very long, often doubling the total length of the giant squid on their own.
In the mouth of the squid is a beak shaped much like the beak of a parrot. The beak is not part of the shell but a separate tooth-like structure.
