The ship's team collected sediments from depths of at least 8 km. It is named after the HMS Challenger, whose crew first sounded the depths of the trench in 1875. Depths beyond 6 km are referred to as the hadal zone. Author: NOAA There are four divisions of the deep sea ocean: the littoral, bathyal, abyssal, and hadal zones. Examples of marine life that live in the deep oceans include prawns (7,000 meters deep), snailfish (7,400 meters deep), and cusk eel (6,500 meters deep). The Earth's oceans range in depth from the surface to more than 36,000 feet deep. The Swedish explorers provided proof of the existence of marine life beyond depths of 6 km.

Challenger Deep is located in the southern end of the Mariana Trench, in the Pacific Ocean, 700 kilometers southwest of Guam. The average depth of the ocean is about 12,100 feet. The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Depths beyond 6 km are referred to as the hadal zone. Challenger Deep is approximately 36,200 feet deep. A Swedish expedition was even more successful in the trawling of a variety of species, which came from 7-8 km deep waters in the Puerto Rico Trench. The bathyal zone ranges from 0.2 km to 3km deep, while the abyssal zone ranges from 3 km to 6 km deep. Do the Atlantic Ocean and the Pacific Ocean Mix. Other creatures include sea cucumbers, snails, hoppers, worms, red prawns, and little pink fish. That's 1.7 miles down!

In addition to Challenger Deep, there are four other deep points in the western Pacific Ocean: Philippine Trench, Tonga Trench, Kermadec Trench, and Kuril-Kamchatka Trench. The bathyal zone ranges from 0.2 km to 3km deep, while the abyssal zone ranges from 3 km to 6 km deep. The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Any ocean depth greater than 200 meters is considered deep sea. The deepest known point is nearly 7 miles below the surface.
