Did you know that less than 5% of the oceans have been explored by scientists?
But we find many curiosities buried under water:
1. Unidentified marine animals (i.e. 2/3 of marine species)
2. Secret military bases
3. Noises emanating from the the depths of the Arctic Ocean: to this day, their origin has still not been be explained by researchers
4. Giant squids that can reach up to 13 meters
5. Underwater cemeteries like Neptune Memorial Reef, in Florida
6. Underwater ruins such as those of the island of Yonaguni in Japan
7. Lost submarines and liners
8. Skeletons of decomposing marine animals
9. Statues
10. Marine pollution (especially plastic)
