The Mariana Trench is 35,800 feet deep. The Mariana Trench can hold Mt.Everest inside of it and still have room for water! The Mariana Trench is also less explored than the moon! What animals live in the Mariana Trench? How do they survive at such a high water pressure?

[|Many of the animals that live in the Mariana Trench are microorganisms, although there are animals in the Mariana Trench that aren't microorganisms but they are very small. (6-10 cm)]. The animals in the Mariana Trench are very unique because some of them don't have eyes because they aren't needed. [|Others have a bioluminescent light that looks like a fishing lure so they can capture their prey.] [|Another thing that is interesting about the marine life at the bottom of the Mariana Trench is that they have an average lifespan of 100 years.] [|Many of the animals in the Mariana Trench are unique because they are able to survive in 2 degrees - 3 degrees of weather. There are many bacteria that live at the bottom. They are cold psychphrillic, which means they love the cold]. The Mariana Trench is also home to the largest uni-cellular organism.

[|The reason many of the animals in the Mariana Trench can survive is because they are invertebrates].[| Also, the pressure inside of the fish is the same as the pressure outside of the fish. If you were to bring these animals to the surface of the water they would die. The reason for this is because the change in pressure is too quick so their cells would burst.] The pressure in the Mariana Trench is so high, that it feels as if four jumbo jets are stacked on top of you.[| The animals adapt to the pressure of the Mariana Trench by living without a swimming bladder. They can't have a swimming bladder because in the Mhariana Trench it is so deep that it will crush anything with air in it.]

There has only been two descents the bottom of the Mariana Trench. The reason for this being is the cost and the risk of not making it back up alive. The first descent included two people which were [|Don Walsh] and [|Jacques Piccard.] The name of the mission was Challenger Deep, since they were the first people to the bottom, they got to name it the Challenger Deep. The other person that made it to the bottom of the Mariana Trench (Challenger Deep) was [|James Cameron. Along with only the second descent he became the first person to perform a solo voyage to the bottom of the Mariana Trench (Challenger Deep).]

In conclusion, the Mariana Trench isn't known very well but it is very unique with its marine life. It is also very interesting as to how the marine life is able to adapt to such extreme conditions.[| These conditions include freezing temperatures and hydrothermal vents that can go up to 500 degrees fahrenheit.] What interested me a lot about this is the lifespan of the marine life in the Mariana Trench, I wonder how do they live so long.
