Kraken

Kraken was a legendary sea monster, a leviathan sent to prey on unwary ships and mariners. A fearsome creature with tentacles, closely resembling a giant squid, the Kraken was said to be the length of 10 ships. This terrible beast would be a subject of many legends and lore that circulated for centuries on the Seven Seas and the Tertiary Antagonist of Pirates of the Caribbeans:Dead Man's Chest.
