The backs of Lion Turtles are so large that they host their own entire ecosystem on their shell.

When he snaps out of it, and realizes the island he’s sitting on top of is the back of this large creature, he dives into the ocean to communicate with it. In the television series, Aang, the main protagonist, accidentally encounters one of these fearsome creatures when he swims towards a floating island just off the coast in a trance. This mythical sea monster exists in the world of Avatar: The Last Airbender, but unlike other creatures on this list, this gigantic half-chimera/half-turtle animal is pretty benevolent. Cetus later lent its name to a constellation and also showed up to menace Sinbad’s crew in the animated film Sinbad: Legend of the Seven Seas. Certainly sounds a lot like the Kraken of Clash of the Titans. They chained her up to a rock, but she was saved when Perseus slew Cetus-in some versions of the story, he did this using Medusa’s head. The King and Queen consulted an oracle and were told to sacrifice Andromeda to the monster in order to spare their kingdom. When Queen Cassiopeia pissed off Poseidon by claiming that she and her daughter Andromeda were more beautiful than the Nereids, sea nymphs who accompanied Poseidon, he punished them by sending the sea monster Cetus to attack Aethiopia. The version of the Kraken that shows up in Clash of the Titans may have been inspired by the mythological Cetus, taken from the Greek word kētos, meaning a large fish or sea monster.

The second Pirates of the Caribbean movie featured a more mythologically-accurate depiction of the Kraken, while the 2010 remake of Clash of the Titans boasted a critter that was something of a mixture of the two, also incorporating some crab-like elements. While Harryhausen’s Kraken was a humanoid sea monster with tentacle-like arms and a fishy tail, the mythological Kraken more closely resembles a giant squid. The word comes to us from Norwegian, where it means an “unhealthy or twisted animal,” but it entered the popular lexicon when it was borrowed for one of the main antagonist monsters in Ray Harryhausen’s Clash of the Titans. Sea monster names can be confusing, and the Kraken is a prime example.
