Ice is less dense than water so it floats on water. This is useful because it insulates the remainder of the water but also means that aquatic life will not die as they would if water froze upwards.

Why does water freeze only at the top of ponds and not at the bottom-explain in terms of anomalous expansion?
most substances contract, take up less volume as they get colder. This is true of water until about 4 degrees Celsius. From 4 degrees to freezing water expands and takes up less space so that ice floats. the colder water of 4 degrees sinks to the bottom of the pond. The ice on top tends to insulate the water underneath keeping it from freezing.
