Because ice (paradoxically) is actually a very good insulator. Water that is below a layer of ice very, very rarely gets any colder than about 4C, which is too cold for thee & me, but not too cold for many fish, or for most aquatic mammals, which have thick layers of blubber beneath their skin that trap their own body heat and keep them comfortable.
Great question!
(Inuit peoples love to eat blubber and think it delicious, though I'm afraid it tastes rather like candle wax!)

The reason is known as the "anomalous expansion of water".
In lakes and other stagnant water bodies in cold countries, though the temperature is sub-zero, only the surface of the water freezes, but the water beneath doesn't. This allows marine life to survive.

coz only the upper surface of water freezes not the water underneath. so it actually helps to stop heat loss frm beneath and thus aquatic animals survive.
