The cold, clear arctic days result in very little water available for animals to drink.

Arctic Thirst

Thirst is a sign of dehydration, which, if severe enough, can cause death. Consistent cold temperatures in the Arctic cause available water supplies to be locked up in the form of ice and snow, and the air is very dry. Although there is plenty of water in the Arctic, there is often not a drop to drink. This means that Arctic animals run the risk of dehydration. How can dehydration be prevented when there is nothing to drink? Two kinds of adaptations occur: feeding on items with high fat content and specialized breathing structures that minimize water loss.
