Check out these 10 terrifying mythical sea monsters!\r<br>\r<br>- Mega Top Tens\r<br>\r<br>-----------------------------------------------------------------------------------------------------------\r<br>\r<br>Just what is a “sea monster” anyway? Well, weve given ourselves a pretty broad definition to work with. Heres the Stubby the Rocket definition:\r<br>\r<br>Sea Monster (noun): Any sufficiently awesome water-dwelling creature that we perceive as being monstrously cool.\r<br>\r<br>So, with that in mind, prepare yourself for the greatest A-Z list of sea monsters ever compiled, just below the surface of this blog.\r<br>\r<br>Abe Sapien (Hellboy): An icthyo sapien, transformed as the result of a strange ritual.\r<br>\r<br>Aquaman (DC Comics): Sovereign of the sea who can breathe underwater and can communicate with sea creatures (either in their own language or telepathically—pretty cool either way).\r<br>\r<br>Afanc (Welsh Mythology): A lake monster who is sort of like a crocodile, beaver or a dwarf.\r<br>\r<br>Bloop (Real Life): Mysterious, extremely powerful, ultra-low frequency sound detected by NOAA. No one knows where it comes from. Probably a monster.\r<br>\r<br>Cetus (Greek mythology/constellation): Most of the sea monsters taken out by Heracles and Perseus were referred to as “Cetus,” which could mean an extraordinarily big fish, shark or sea monster.\r<br>\r<br>\r<br>Charybdis (The Odyssey): Basically a giant whirlpool (or monster who causes massive whirlpools) designed to screw over Odysseus.\r<br>\r<br>Creature from the Black Lagoon (Creature from the Black Lagoon): A Gill-Man who only wants to be left alone.\r<br>\r<br>Cthulhu (H.P. Lovecraft): One of the Great Old Ones. Part octopus, part human, part dragon, all badass. Watch out.\r<br>\r<br>Fiji Mermaid (Real life): A sideshow creation consisting of the top half of monkey and the lower half of a fish.\r<br>\r<br>Hydra (Greek Mythology/Real Life): The Lernaean hydra was a many-headed, serpent-like beast killed by Heracles. Also a genus of tiny, predatory, fresh-water animals with regenerative abilities.\r<br>\r<br>Jörmungandr (Norse Mythology): AKA, the Midgard Serpent, offspring of Loki and Angrboða and archnemesis of Thor. When he lets go of his own tail the world will end.\r<br>\r<br>Kappa (Japanese Folklore): A water sprite. Sometimes hairy.\r<br>\r<br>Kelpie (Celtic Mythology): A water horse with ghostly trappings. Sometimes appears as a beautiful woman. Not to be trusted.\r<br>\r<br>Koizilla (Avatar: the Last Airbender): At the end of season 1, Aang fuses with La, the Ocean Spirit to become Koizilla: the wrath of the ocean embodied in awesome fish-monster form.\r<br>\r<br>Kraken (Greek Mythology. Also, real life.): Sometimes referred to as the giant squid. But also a thing released in Clash of the Titans. (Dont release it!)\r<br>\r<br>Leviathan (The Bible): The Original Biblical Sea Monster. Hangs out near the Hellmouth.\r<br>\r<br>Lion Turtle (Avatar: the Last Airbender): Giant, ancient, looks like an island, gives pretty great advice.\r<br>\r<br>The Little Mermaid (Hans Christian Andersen/Disney): The heroine of one of Andersens most beloved tales, the Little Mermaid falls in love with a human prince, and…well, the Disney version is much less complicated. Very big in Copenhagen.\r<br>\r<br>Makara (Hindu Mythology): Any creature that is half land animal on top with the bottom half of an acquatic creature; so: person + seal, or wildebeest + whale. Makara!\r<br>\r<br>Marsh-wiggle (Narnia Chronicles): Extremely private, pessimistic humanoid creatures that live in the marshes of Narnia. \r<br>\r<br>Mega Shark (Mega Shark Vs. Giant Octopus, Mega Shark Vs. Crocosaurus): A large Shark who is the sworn enemy of Giant Octopus, Crocosaurus and good taste.\r<br> \r<br>Melusine (European Folklore): Female spirit who hangs out in springs and rivers.
