The Southern Ocean is liquid under its frozen top, and these animals are adapted to the extreme cold, some with versions of anti-freeze in their systems.

Why don't fish in Antarctica freeze?
Antarctica is a continent. In Antarctic waters, which are liquid, the fish survive there because it's their natural habitat. When the sea ice freezes, the fish simply migrate so that they remain in liquid.
What food comes from the Antarctic?
No food is grown on Antarctica. There are, however, fish that are harvested from waters north of 60 degrees S, that are sometimes called 'Antarctic fish'.
How long does a Black dragonfish live?
the antarctic waters deep under the Antarctic waters where it is dark.
What does ice fish mean?
An ice fish is a species of fish that lives in the Antarctic. It has anti-freeze blood to stop the fish from dying.
What is the world's coolest fish ever?
Those that live predominantly in Arctic or Antarctic waters.
How do you catch a fish in Antarctica?
There is no subsistence fishing there, or commercial fishing allowed in Antarctic waters.
What is an Antarctic fish?
Antarctic cod, mackerel icefish, and Antarctic toothfish are three species of fish having certain properties of 'antifreeze' proteins contained in their blood that enable them to survive in temperature where 'normal' tissues would freeze.
How would frigid Antarctic waters affect the ice fish's need for oxygen?
Antarctic waters are higher in oxygen content than are other oceans. This means that oxygen is more freely available to these animals in the Southern Ocean.
Why must arctic fish produce anti-freeze chemicals to survive in icy waters?
because so they cant freeze to death
What do erect-crested penguins eat?
Erect-crested penguins feed on fish and krill found in sub-Antarctic waters and the waters around New Zealand.
What level of the ocean do Antarctic ice fish live in?
Not only does it depend on the species of fish it also depends on the predators too.
What kind of fish are there in antarctica?
Most of the fish in Antarctica belong to the Notothenioidea group. There are four types of fish in this group including the Antarctic cod, the Dragon fish, the Plunder fish, and the Ice fish. Out of these four, the Ice fish is the most unusual because of how it has evolved to survive in the harsh, icy waters of the Antarctic. This cold blooded fish lacks haemoglobin, the red pigment found in blood which transports oxygen throughout the body. Instead, the oxygen is carried in the plasma. The absence of haemoglobin in its blood allows the Ice fish to produce more glycoprotein, a chemical which acts as a type of anti-freeze in the fish's blood, preventing them from freezing. Other fish in the Antarctic include the eel-pout, tooth fish, and snail-fish.
