16 Things No One Knows About The Ocean

Welcome to the last frontier on Earth. Sure, the oceans are terrifying and the Kraken might have been real, but the things we don't know could fill a thousand documentaries on the Discovery Channel.

2. No one knows what made this sound.

While the most famous mystery underwater sound — the Bloop — is consistent with (read: probably) some underwater icequake or another, no one knows for sure what made this sound, nicknamed Julia. So it might be Cthulhu. You don't know.


7. Mysterious rivers and lakes exist underwater, with creatures found nowhere else.

Some of these brine-filled rivers and lakes have mussels living around them, and some don't. Why don't some have mussels? Why?

(Brine is super salty and way more dense than water, so it sinks and forms these pools and streams. SCIENCE.)


9. How much fish would a fishery fish if a fishery could fish deep-sea marine habitats?

We're not really sure how deep-sea fishing affects the ecosystem due to a lack of data. So maybe we'll be eating ghost shark in 50 years because it tastes like rainbows, or maybe catching a lot of ghost shark would be super bad for the ocean.

11. In the Triassic period, the Kraken may have eaten bus-sized Ichthyosaurs.

Yes, a giant, murderous squid-like creature is the supsect behind a pile of Ichthyosaur bones found in the Nevada desert. And -- to add a dose of CREEPY -- the bones look like they were ARRANGED. The Kraken either drowned or broke the necks of its victims, and then PLACED them in an alternating double-line pattern like suckers on a tentacle.

In summation: scientists hypothesize that a giant sea monster killed other giant sea monsters and made self-portraits with their lifeless bodies.

12. We know about seven underwater waterfalls, but there could be more.

In the sea between Greenland and Iceland, where some frigid water mixes with less frigid water, lies what is technically Earth's largest known waterfall: 175 million cubic feet of water per second (2,000x Niagra Falls) dropping 11,500 feet (3x the height of Venezuela's Angel Falls, above).
