How aquatic animals survive in water during winter?
When water boils at a certain temperature it turns into steam. 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.
What happens to animals when lake freezes?
When an entire lake becomes oxygen starved, winter-kill events take place. As the anoxic zone creeps upwards into the water column, fish cling to the under-surface of the ice as the oxygen is depleted, until they suffocate to death.
