Only the tops of the rivers and lakes freeze. The animals living in the water still live a liquid of water while the tops are frozen but under it is water. Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds.
Animals like seals, penguins, walruses and a wide variety of sea birds are all fish eaters. They live in the Arctic and Antarctic Circle, amidst the icecaps. The land is completely frozen. Yet these animals manage to live in this region. How do they do it?
The icy waters of the Arctic and Antarctic Oceans support a great amount of marine life. For millions of years life has remained unchanged, making it possible for these animals to adapt themselves to these particular patterns of existence.

Animals such as fish etc, have evolved to combat the cold. For example fish have a thick mucus layer around them that acts as insulation. As well as this the fish will stay towards the bottom of the lake where it is warmer.
