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.
Antarctica is a continent. Fish are sea animals. The Southern Ocean habitat -- that surrounds the Antarctic continent -- is native to fish that survive and thrive there.
the ocean
No. Puffer fish can only survive in the ocean.
kills creatures habitat eg fish
Blob fish survive by laying on the bottom of the ocean floor and eat anything that floats by!
I thinks it is in the ocean or on the beach.
so we can have water and we need to survive and also eat fish
They posses adaptation feature to the marine habitat.
fish, coral, treasure(Maybe)
Whales are mammals and normally give birth to live young ones. Their habitat is the sea where they are adapted to survive in.
food and a way to breath
Whales are sea animals and Antarctica is a continent. Whales survive in the Southern Ocean -- which surrounds Antarctica -- because it is their natural habitat when the ocean is free of ice.
