The deep ocean is considered to be anything below the photic zone, which only extends a few hundred meters down into the ocean’s waters, and this huge area is home to all of the deep ocean fish. These fish have special capabilities that allow them to live at high pressures and to survive cold ocean water. Most of these deep ocean fish cannot live in any other environment so not much is known about their behavior.
There is no natural light in the deepest part of the ocean so fish there have different ways of intuiting what is going on around them. Some deep ocean fish are bioluminescent, which means that they have extra large eyes which have adapted to the darkness. Other fish have evolved to have feelers which help them to find food and others of their own kind with which to mate.
The angler fish is so named because it has a fishing-pole-type object that protrudes from its face, and on the end is a small piece of skin which can wiggle like a worm to attract prey. Because there is no photosynthesis under the ocean, any plant matter that fish may need for nutrients has to sink down from above. On the whole, this makes deep ocean fish smaller in overall size and weight but with larger mouths than their counterparts who live higher up in shallower water.
Many deep ocean fish that live far down below are jelly-type fish. One such fish is the blob fish which has no muscles and looks like a blob of jelly with a face. These fish have no option but to float around waiting for something to eat to pass by. There are thousands of species of deep ocean fish and most of these are darkly colored to blend in with their surroundings and not attract predators.
The further down into the ocean you go, the more you find a couple of different kinds of fish–those who stand and wait like the blob fish and those who can swim. Swimmers have to have gas bladders or be extremely light. Many are eel-looking in appearance. One such group of fish are the rat-tails, who have big heads and then their bodies taper down to nothing by the time the tail is reached. They are related to cod and there are an incredible two hundred species of this type of fish alone. They eat mostly mollusks, crustaceans and worms.
An example of standers are the bottom-dwelling sharks, who spend most of their time resting on the ocean bottom. They must keep moving at all times so that air can be forced through their lungs. They wait for their prey to come along and ambush them whenever possible. If these sharks or other standers stopped swimming they would perish.
