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.
