Feeding on detritus, amphipods are true bottom feeders. They eat debris from decaying plant and animal matter that floats to the bottom. They have been found as deep as 9,100 meters below the ocean surface.

The hadal zone is the deepest region in the ocean, extending from 6,000 meters to 11,000 meters below the surface. The first manned exploration to reach Challenger Deep, the deepest known part of the ocean located in the Mariana Trench, was accomplished in 1960 by Jacques Piccard and Don Walsh.
This zone does not spread across the ocean floor but exists only in the deepest ocean trenches.

Benthescymus crenatus was the most well represented species at this point in the hadal zone.Also known as a grenadier, these fish were found at 7,000 meters. This zone does not spread across the ocean floor but exists only in the deepest ocean trenches. Because no light reaches this part of the ocean, it is impossible for plants to thrive but there are still hardy creatures that call these depths home. Found in both the Kermadec and Japan trenches, decapods were spotted actively hunting amphipods. Rat-tails have large mouths and a tapering tail which makes them look like giant tadpoles. The hadal zone (named after the realm of Hades, the underworld in Greek mythology), also known as the hadopelagic zone, is the deepest region of the ocean lying within oceanic trenches.

‘Submarine trenches usually develop downward from depths around 6,000 m, the beginning of the hadal region, exclusive domain of highly specialized and exquisite molluscan communities.’ ‘The hadal zone makes up only 1 or 2 percent of the ocean and is located in narrow oceanic trenches.’
