You can ask the biggest expert of marine life and biology about the ocean, and even he or she wouldn’t be able to tell you what exists in the deepest parts of the ocean.

The Mariana Trench is the deepest part of the ocean, which has been established by experts, but what about the rest of the ocean? What’s the second deepest part of the ocean? Or the third, fourth, and fifth. What’s down there that nobody talks about? It’s no doubt that new species of marine and plant life get discovered every single day. That is especially true for the mass-unexplored part of the deep as the Mariana Trench.

Covering 70% of the world, there is no single person who will be able to explore the entire ocean in one lifetime, which is why, even with the technology we have today, there are many unexplained answers.

How Much of the Ocean is Unexplored?

According to Oceana, over 80% of the ocean remains unexplored because humans need oxygen to survive, which makes it very intricate and costly to go deeper down in the depths of the ocean.

Today, scientists are under a lot of pressure to find and discover new places. Not only in the water but also among the stars in space. Scientists and marine biologists have found that the deeper you go into the ocean, the less fish, invertebrates, and crustaceans look like what we know due to a lack of sunlight in the depths.

Creatures like lanternfish, giant tube worms, fang-mouthed monstrosities, hatchet fish, and gulper eels have thus far been discovered among many other species in the deep dark waters of the hadopelagic zone, which is between 13,000 to 20,000 feet deep. The deepest parts of the ocean remain 20,000 feet or deeper.
