Whale fall community progresses through three stages: [32] Mobile scavenger stage: Big and mobile deep-sea animals arrive at the site almost immediately after whales fall on the bottom.
Biogenous material is the sediment made up of the hard parts of sea creatures, mainly phytoplankton, that accumulate on the bottom of the ocean. Hydrogenous sediment is material that precipitates in the ocean when oceanic conditions change, or material created in hydrothermal vent systems. Cosmogenous sediment comes from extraterrestrial ...
At the other end of the spectrum, benthos of the deep ocean includes the bottom levels of the oceanic abyssal zone. [7] For information on animals that live in the deeper areas of the oceans see aphotic zone.

Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep-sea fishes include the flashlight fish , cookiecutter shark , bristlemouths , anglerfish , viperfish , and some species of eelpout .
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches.The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions.
