Kraken

Considered to be one of the largest ocean creatures, krakens live in the depths of the Norwegian Sea. They rise to the surface, preying on unsuspecting whales and ships. The long sucker-covered tentacles latch onto the victim, crushing bones or boards under the weight. The two longest tentacles are feeder arms, grabbing bits of food and bringing it to the hard beak. A thick bone shell protects the head and organs of the creature, making it nearly impossible to kill. The immense eye is the only weak point. Despite its large size, the Kraken is a fast swimmer, sometimes reaching speeds of 35 mph. However, after feeding, it prefers to use its weight to sink back into the ocean depths.
