So the Deepest Point on Earth, What's in the Mariana Trench?



The highest point of the world is the summit of Mount Everest in the Himalayan Mountains, friends.

What about the lowest point in the world, huh? The deepest part of the Earth is the Mariana Trench in the Pacific Ocean, friends.

So deep, to the point that there is no light in the Mariana Trench, lo.

Wow, about there is no life huh, there? Let's find out what can be found inside the Mariana Trench, huh?

Weird creatures on the seabed

According to scientist Douglas Bartlett who has carried out deep sea expeditions, the most visible are sediments of gray-green sediment.

But, if there is food placed there, living things will begin to appear.

Yep, apparently at the deepest point on Earth there is also life!

However, living things that live in the deep sea are usually unique and even strange creatures. Anything?

Amphipod

One unique creature on the seabed is amphipod, which is a crustacean animal.

Although the body is similar to shrimp and lobster, amphipod can grow as long as 30 centimeters, lo.

Amphipod has an exoskeleton made of potassium carbonate. Potassium carbonate is usually not found at a depth of 10,000 meters below sea level.

The reason is that, under a depth of 4,500 meters, the pressure in the water is getting higher and the temperature is very low. So that calcium carbonate can dissolve in water.

Then, how can amphipod live there?

Amphipod has a secret shield, lo, which is an aluminum layer made on its body.

Aluminum is sourced from aluminum on the seabed.

Apparently, amphipod needed the shield to protect itself from other creatures at the deep sea point.

Mariana Snailfish

In the darkness of the Mariana Trench, there are creatures that lurk amphipod, the Mariana snailfish.

Mariana snailfish is a fish found living in the deepest point.

Scientists have seen it swim to depths of 8,000 meters below sea level.

Even though it looks like a normal fish, the Mariana snailfish has flexible bones. According to scientists, the flexible bones helped him survive with such intense pressure in the deepest trenches.

This Mariana snailfish is blind, friends. In addition, in the part of the sea where he lives there is also no light that can help him see.

The fish also has transparent skin so that its organs can be seen from the outside.

Although not large in size, the Mariana snailfish is a first-rate predator in the deep sea.

One-cell organisms in the Mariana Trench

In addition to the Mariana snailfish, there are also other strange creatures, namely xenophyophore.

Xenophyophore is a single cell organism that looks like an amoeba, but has a large size.

The creature consists of only one cell but its size reaches 10 centimeters. It is the largest single cell organism on Earth.

Sea Cucumber "Sea Pigs"

The animal, called the sea pig, is actually a transparent sea cucumber crawling on the seabed.

Its body is shaped like an insect and its legs are like tentacles, friends.

Plastic waste

Yep, even though far from humans on land, plastic waste is also found in the Mariana Trench, the deepest point in the world.

In 1998, scientists detected a plastic bag at a depth of 10,898 meters below sea level. Then in 2019, scientists said there was more plastic debris at a deeper point.

In fact, microplastics are also found in the stomach of the amphipod in Challenger Deep, the deepest point of the Mariana Trench.

Sad, huh? This means that humans have dumped too much garbage that ends up in the sea to pollute the deepest places on Earth.

C'mon, friends, we reduce the use of disposable items so they don't become rubbish and can end up in the sea.
