The video discusses the possibility of the Megalodon shark still existing in the deep ocean. The host, Ivan, explains that the Mariana Trench, the deepest point in the ocean, is home to a diverse range of animal and plant life, despite the extreme conditions. He mentions that only three people have descended to the bottom of the trench and that the pressure is 1,000 times greater than at sea level.
Ivan discusses the Megalodon, a prehistoric shark that is believed to be extinct. He explains that some people believe it may still exist in the deep ocean, but scientists think it is impossible for the shark to survive in such depths due to its size and feeding habits.
The host also talks about the discovery of the bigmouth shark, which is a deep-sea shark that can live in waters up to 7 km deep. He explains that sharks are not just mindless predators, but play a crucial role in maintaining the balance of the ocean ecosystem.
Ivan concludes that while the idea of Megalodon still existing is exciting, it is unlikely to be true, and that the deep ocean is still a largely unexplored and mysterious environment.
Here are the key facts extracted from the text:
1. The Mariana Trench is the deepest place in the world.
2. The Mariana Trench is located in the eastern region of the Mariana Islands in the southwest of the Pacific.
3. Only three people have descended to the bottom of the Mariana Trench.
4. The pressure at the bottom of the Mariana Trench is a thousand times greater than the pressure at sea level.
5. The region is home to a diversity of animal and plant life, including invertebrate animals and fish.
6. Some species in the region are more common, such as sole, while others are rarer, such as anglerfish.
7. In 1985, researcher Roberto Balla identified the presence of different beings in the depths of the region.
8. The snail fish has been found 7 km and 966 meters deep in the Mariana Trench.
9. Scientists believe that after a certain depth limit, other types of fish cannot exist.
10. The bigmouth shark can live in deeper waters because it feeds on plankton.
11. The bigmouth shark was first seen in 1976 and has been recorded 50 times since then.
12. There are around 375 species of sharks spread throughout the world.
13. In Brazil, 80 species of sharks have already been identified.
14. Records of the first sharks date back to more than 400 million years ago.
15. Sharks play a fundamental role in the biological balance and for cleaning the oceans by swallowing dead animals.
16. Sharks have a great sensory capacity and can identify the presence of a drop of blood even 30 meters away.
17. The Greenland shark can live up to 400 years.
18. A study published in the journal Science in 2016 confirmed the age estimate of the Greenland shark.
19. Megalodon was a carnivorous animal that lived in all parts of the oceans and was the largest predator of marine life.
20. The estimate is that a shark of the Megalodon species could reach 20 meters long and weigh between 50 and 75 tons.
21. Megalodon means "big tooth" and its teeth were huge, almost the size of a banana.
22. Megalodon fed on whales, dolphins, seals, and probably other sharks.
23. The estimate is that Megalodon needed to eat around 900 kilos per day.
24. Scientists believe that it is impossible for Megalodon to survive hidden in the depths of the ocean.
