Fish that live at great depths live virtually the same as fish that live near the surface, with a few differences.
-Fish from deep waters typically lack much color, and some are completely translucent.
-Fish from deeper waters often use bio-luminescence to attract mates and their prey.
The deeper the water is, generally the less oxygen there is dissolved in the water.
To combat this, deep-water fish are often small, and have highly efficient gills. They are also relatively inactive compared to higher level fish.
As far as the pressure is concerned, they are acclimated to it. Similar to the way a diver will acclimate to depths. The oxygen in the blood compresses, nitrogen bubbles form, and basically you are fine until you decide to resurface. You start having problems when you ascend in the water column to rapidly, and the dissolved oxygen in your blood expands by as much as 10x's (this is only from very deep dives mind you), but this is very rarely experienced, as you need to dive to a thousand feet or more to experience that drastic of a change.
Any animal has to ascend slowly through the water column. When a diver dives below 40' for more than 10 minuets he or she has to pause @ 15' to acclimate to the lower pressure for several minuets. Fish have to go through the same process, but when an angler catches a deep water fish, the fish is not allowed to decompress there for it balloons up.

∙ 6y agoI think its because they are really loose! I heard that if you take a fish thats use to the water pressure out of the water, it will like explode well actually it's organs will come out its mouth because the water pressure holds it together thats why you never see some fish at the surface.
hope I helped

Their anatomy allows their bodies to adjust to pressure-changes, but they are not "held together" by the water pressure. Their own structure does that, just as ours hold us together.

I'm not sure its death will be quite that gruesome but bringing a deep-water fish to the surface too rapidly may well kill it.

∙ 14y agoThey have adapted to live in water. depends how big the fish is but they have gills and it depends what kind of fish it is

∙ 11y agofish use their gills to survive in their habitat.
