When I stepped outside this morning, I heard frogs for the first time this season. Quite a chorus. This is the first spring season I have lived in the Swamp Castle, so I have been looking forward to going to sleep to the frogs.

Then I got to thinking, how to frogs spend the winter? With the internet, the answers are never far away.

Frogs estivate. Their body systems slow down to a virtual halt. Contrary to what I thought, they usually do not burrow into the muck in the bottom of a lake. Instead, they hide under a log or branch and go to sleep. Their heart can stop, they can stop respirating--and most amazingly, they can even freeze quite solid and still wake up when spring comes.

Also found out that turtles burrow in the mud and spend the winter absorbing oxygen out of the mud through their skin.
