There are countless stories of mythical creatures and legendary monsters throughout history. Despite their origins are unknown, these mysterious creatures have a place in folklore and in many cases are part of pop culture. Here are the scariest mythical sea monsters that might actually existed.
Leviathan
Legend states that the Leviathan combines two of Earth's natural elements to take the lives of innocent sailors. This fire-breathing sea monster was known to be able to make the water around itself boil. This allowed it to kill its prey and generally terrorize humans. The Leviathan even is mentioned in the Bible where it was referred to as a savage primordial sea serpent feared for its ruthless nature and cruel behavior.
Kraken
According to Scandinavian mythology, the Kraken is a legendary sea monster of gigantic proportions said to dwell off the coasts of Norway and Greenland. The Kraken is usually described as a giant squid or octopus-like creature, but it has also been described as crab-like. There are various tales of the Kraken attacking and destroying ships. They also capable of making giant whirlpools. It is believed that the myth of the Kraken could have originated from giant squids which could grow up to 18 meters long and were rarely seen by humans.
According to Terry Breverton in his book Phantasmagoria: A Compendium of Monsters, Myths, and Legends, before there were mermaids, some 4,000 years ago there was a merman: Ea, the Babylonian god of the sea. He had the lower body of a fish and upper body of a human, and was one of those handy all-purpose deities, bringing humankind the arts and sciences while also finding the time to battle evil. And because he was associated with water, he was the patron god of—no joke—cleaners because, well, someone needed to be. Ea would later be co-opted by the Greeks as Poseidon and the Romans as Neptune.
The earliest mermaid-like figure was likely the ancient Syrian goddess Atargatis, who watched over the fertility of her people, as well as their general well-being. She, too, was human above the waist and fish below it, and was accordingly associated with water. The Syrians bestowed Atargatis with the biggest, most resplendent temple they could muster, which came complete with a pond of sacred fish that you probably weren’t allowed to throw coins into for a good luck.
