Alaska has two native frogs: The Wood Frog and the Columbia Spotted Frog. The wood frog is the only amphibian found north of the Arctic Circle. This amazing little creature will have 65% of the water in its body freeze solid during our harsh winter months. The frog’s heartbeat and breathing will completely stop. Yet, the frog will survive.
When autumn comes, the wood frog starts to build up a glucose in its cells. Its blood turns into a syrup-like substance, a natural glycol, if you will.
In the spring, the frog will thaw along with its surroundings, and then hop along on its way.
