The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.
It is apparently the top predator along certain stretches of the Mariana Trench, feeding on tiny crustaceans in a deep-water habitat with few larger predators. [4] Pseudoliparis swirei are abundant in their deep-sea habitat and lay relatively large eggs that are almost 1 cm (0.4 in) in diameter.

The deepest part of the deep sea is Mariana Trench located in the western North Pacific. It is also the deepest point of the Earth's crust. It has a maximum depth of about 10.9 km which is deeper than the height of Mount Everest. In 1960, Don Walsh and Jacques Piccard reached the bottom of Mariana Trench in the Trieste bathyscaphe.
Oceanic trench formed along an oceanic-oceanic convergent boundary The Mariana Trench contains the deepest part of the world's oceans, and runs along an oceanic-oceanic convergent boundary. It is the result of the oceanic Pacific plate subducting beneath the oceanic Mariana plate .
The Mariana Trench is the deepest point on Earth, void of light with the pressure of 48 jumbo jets. Yet life finds a way to survive. Very weird life.
Location of the Mariana Trench: an example of a hadal zone. Hadal zone microbial communities are the groups of microorganisms which reside within hadal zones, which consist of many individual deep oceanic trenches found around the world. [1] The environmental conditions of the trench environments select for the microbe communities.
The Scripps Institution of Oceanography deployed the 1,490-ton Navy-owned, civilian-crewed research vessel Thomas Washington (AGOR-10) to the Mariana Trench on several expeditions from 1975 to 1986. The first of these was the Eurydice Expedition, Leg 8 which brought Fisher back to the Challenger Deep's western basin from 28–31 March 1975. [ 33 ]
