Mermaids don’t exist but that doesn’t mean the ocean fall short of mystic stories to tell. Scientists and explorers believe there is still a lot we need to unravel in the depths of the ocean as 95% of it still remains unexplored. Why? Some experts say deep sea exploration is much arduous compared to exploring the outer space. In fact, more men have stepped on the moon than dived into the depths of Mariana Trench, one of the deepest parts of the world.

But what’s really down there? What can we find hundreds or thousands of feet below sea level? We have listed some of the most intriguing mysteries we can find under the sea.

Underwater Lakes and Waterfalls

The grand underwater waterfall is believed to be much higher than Angel Falls, the highest waterfall on earth at 3,212 feet. There are also lakes on the ocean floor that are 300 feet deep, which is believed to host species that cannot be found in other parts of the ocean. Also, it is believed that the sea floor is highly undulated, with mountain ranges and valleys. It is even estimated to have more valleys that are much deeper than those in Grand Canyon. There is also a wide variety of sea creatures yet to be discovered.

Lost City

A lot of stories and theories about the lost city of Atlantis are wild beyond belief. Many people believe it did exist. But Atlantis was an allegory of Plato – a product of his imagination. Or was it really? A historian named Bettany Hughes has been researching the ancient myth of Atlantis believed that Plato got the idea from somewhere.

In the region of Peloponnese, in Greece there is a small village called Pavlopetri where you can find an ancient city dating back 5,000 years resides. Scientists estimate that the city was sunk in around 1000 BC due to some catastrophic earthquakes. However, despite this and even after 5,000 years, the arrangement of the city is still clearly visible and at least 15 buildings have been found.

Immortal Jellyfish

A certain species of Jellyfish seems to have a “Benjamin Button” kind of phenomenon. They do reproduce and die in an expected way but once they see a serious trauma, they have the ability to reverse the aging process and start evolving to become their younger selves. This lets them heal and survive from stress. Currently, they start to overpopulate certain parts of the ocean, making it hard for other marine life to breed.

The North American – Eurasian plate

Some photos show the gap between Europe and North America is getting wide! The place is known as Silfra Crack, in Thingvellir National Park in Iceland. This place is a dream site for divers. This is because you can see two continental plates meet and pull apart. The tectonic plates are drifting away one inch per year. Many who have dived here did say it was an unforgettable experience.
