This is due to one of the wonders of the natural world.
If water behaved like any other liquid, then when the air temperature was below zero, lakes and ponds would quickly freeze solid, from the bottom up. But water has ANOMALOUS EXPANSION such that it is densest at 4 degrees C, not at its freezing point, so a skin of ice forms at the top - as everybody knows - and everything under that stays at a steady 4 degrees C, which is just enough above zero to be livable in.

Most of the animals that live in the cold waters have a glycol protein in them ,which resist freezing. The Eskimos get the benefit from eating them.

Usually, only the top 1-2' freezes (here anyway). The rest of the water is at least 32 degrees (duh). Deeper you go, typically warmer it is. They just deal with the cold.
