20 strange and scary facts about the ocean that you will learn today (6 photos)

Most of the earth's surface, namely 71 percent, is covered with water, and many secrets lurk under the water, because we have only been able to study 5% of what is at the bottom.





The unknown is both frightening and exciting, so we've compiled these fascinating facts about what lies beneath the ocean's depths.

1. Greenland sharks can live more than 500 years

Greenland sharks live more than 500 years, swimming and hiding underwater. However, despite their long lifespan, they only reproduce until they are 18 years old.

2. Blobfish look different in photos than they do in water.



When scientists first discovered the blobfish, they didn't know that it was not as tenacious as other deep-sea inhabitants and pulled it to the surface too quickly.

Due to the sudden change in pressure, her skin burst and her flesh was damaged, so in the photo she looked completely different from how she looked at the depths.

3. Lobsters are practically immortal

Lobsters don't age the way people age. They are equally active at 5 years old as at 70 years old, and natural death occurs when they can no longer molt.

4. Shark watchers miss most sharks

On ocean beaches you can often see people making sure that sharks do not swim too close to the shore and harm people swimming.

However, sharkologists conducted an experiment by placing underwater sensors and found that many more sharks swam to the shore than the observer was able to detect.

5. Corryvreckan Maelstrom





The Corryvreckan Whirlpool is located in Scotland and is a permanent whirlpool, as well as the third strongest in the world. It can create standing waves up to 15 meters high.

6. Most of Earth's oxygen is produced in the ocean.

We all know that trees produce oxygen and allow us to breathe, few know that most of the oxygen is produced in the ocean by phytoplankton.

7. The sailfish is the fastest fish in the ocean

The Sailfish fish can reach speeds of up to 110 kilometers per hour in water.

8. There are more artifacts in the oceans than in all the museums in the world.

There are more than 20,000 different historical artifacts lying on the ocean floor, and this number continues to increase every year.

9. Beaches in Hawaii are made of fish poop.

Parrotfish nibble and scrape off small pieces of underwater rocks. In her stomach, these stones are not digested, they come out and accumulate; over time, their number became so large that a beach of white “sand” was formed.

10. Many tuna species are becoming extinct

Of the 63 species of tuna, 15 are rapidly declining in population and one is close to extinction.

11. The highest mountain is not Everest



While Everest is the tallest mountain on Earth, in the Pacific Ocean there is a mountain called Mauna Kea, whose base is on the ocean floor and its height is 10,211 meters.

12. The Pacific Ocean is shrinking over time

The Pacific Ocean gets a little smaller every year, and the Atlantic Ocean gets a little bigger. This happens because the North American tectonic plate is constantly moving westward. Given enough time, the US West Coast could meet Asia.

13. Crustaceans and worms live in hydrothermal vents

Spontaneous thermal springs support their own microcosms of crustaceans and worms. When the spring vents become inactive, everything dies, leaving a graveyard of underwater worm shells.

14. The Atlantic and Pacific oceans differ in height

There is a difference in water level between the Pacific and Atlantic Oceans, the Pacific Ocean is about 40 centimeters higher than the Atlantic Ocean.

15. Most ships cannot survive encounters with rogue waves.



Most ships cannot survive encounters with rogue waves. The existence of rogue waves was denied until one was filmed on an oil rig in the North Sea, as they caused most ships, especially tankers and cargo ships, to sink.

16. Sea cucumbers make up most of the biomass on the abyssal plain

Sea cucumbers make up the majority of the biomass on the abyssal plain, which in turn occupies about 40% of the ocean floor.

17. There is as much energy in the upper layer of water as in the entire atmosphere

Due to the large specific heat capacity of water, the same amount of energy is stored in a three-meter layer on the surface of the ocean as in the entire Earth's atmosphere.

18. The ocean floor is covered with dead and decaying organisms and feces of living organisms.

Thanks to rising currents, snow is constantly falling on the ocean floor, consisting of dead and decaying organisms and feces of living organisms. It's called "sea snow".

19. We know more about the surface of the Moon than the ocean floor

Because we can't just look through a telescope and photograph the ocean floor, and going deep is difficult because of the very high pressure, it was much easier for us to study the surface of the Moon, which we now know more about than the ocean floor.

20. Tiger sharks grow over 5 meters



Tiger sharks are the most common shark on Earth and average 3 to 4 meters in height, but can often grow to over 5 meters. Such sharks weigh more than a ton. The confirmed weight of the heaviest tiger shark was 1,524 kilograms.
