A Kraken is an enormous sea monster which would sometimes attack ships and feed upon the sailors. It was supposed to be capable of dragging down the largest ships and when submerging could suck down a vessel by the whirlpool it created. It is part octopus and part crab, although others refer to it as a giant squid or cuttlefish.
