Deep sea
There are many types of saltwater fish. Coastal fish live in the ocean near the shore. Deep sea fish live deep in the ocean below where the sunlight reaches. Pelagic fish live near the surface of the ocean. Demersal fish live near the bottom of a salt lake or sea. Coral reef fish live in or near coral reefs.

The Viper fish is one of the fiercest predators of the deep. It lives in the deep parts of the sea.
Grenadiers, better known as rattail fish, live deep in the arctic and Antarctic ocean waters. These fish were part of the most abundant in deep-sea fish families.
They live in the sea! Of course they are near other animals, yet they do live in the deep sea.
On the deep sea floor in temperate regions of the world
There are many fish in the sea...
Deep sea angler fish live in all oceans deep enough for their life, salinity, and preasure limitations. They have been found in all deep seas.
Fish survive in the ocean by their gills. Fish need oxygen too, just like many other living things. They do not breath the water. Their gills receive oxygen and they breath that way. that's why fish CAN live under water. 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 fish include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, and viperfish.Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor.Deep-sea organisms generally inhabit bathypelagic (1000m-4000m deep) and abyssopelagic (4000m-6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200m-1000m deep) zone as well.

The sea nettle jellyfish are mostly found in the Atlantic Ocean and the Pacific Ocean. They prefer to be in the colder ocean waters.
