In antartic region,what happens to the fishes when the sea is frozen?

Even if the sea becomes frozen the fishes in the antartic regions have a special anti-freeze which donot allow their internal organs to freeze even if their outer scales start freezing i.e all the processes are going inside their bodies.

well ICE that forms on the ocean floats on the surface and fish live below that ice in the water with is not freezing. These fishes have developed certain compounds in there blood that prevents it from freezing and from froming crystals. in this way they can survive in the cold antartic region

the temperature of water deep down the ocean does not go below 4 degree celsius. So, water does not freeze and that provides a normal environment for the cold-blooded fishes to survive.

creation of this world is such that each n every animal on this planet adapt themselves according to their enviornment, and here ur talking abt the fishes of antartic ocean do their body is build up such that they can live in such an enviornment,we worry abt it bcoz we cant live in such env. but think the fishes must b thinking how do these humans live in hot or warm env. isnt it and over all the water freezes only at surface n the inner water is warm enough to keep them alive n fishes are cold blooded animal they can adjust their body temp acc to env, and they r also provided wid some fluid in body which help them to survive in such cold conditions.........as i said creation is well maintained

Actually certain species of fish in the antarctic has antifreeze in their bodies that keeps them from turning into ice.

The density of ice is less than water so in the cold regions the upper layer of water converted into a thin layer of ice not the whole sea.Inside this layer their is a suitable environment for survival of life.

suspended animation, they just slow down and wait till the water gets ready again.

the sea only freezes on the surface the fish can live under the ice.

Fish are cold blooded, meaning that like reptiles, their body temperature is the same as their outside temperature. So, when water gets really cold, so does the fish. This slows down the fishs' metabolism (how fast they use up food and energy). So, when water is cold enough to freeze, a fish's metabolism is REALLY slow, almost as slow as an animal that was hibernating, so the fish doesn't need much air or food. Baisically, the fish is hibernating, but it's because of how cold it is, not because that's when it's internal clock tells it it's time to.
