In cold winter months, lakes and rivers freeze over forming ice. Yet, fish and other aquatic animals manage to survive.
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.

Hi mate
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. This irregular expansion of water is called anomalous expansion.
Hope it helps you....
