If you kiss me ....


.... maybe I'll turn into a beautiful princess! LOL, I couldn't resist posting this tiny Wood Frog (Rana sylvatica) sitting gazing at friend David : ) I thought the hand would give a perfect sense of how small these frogs are. The Wood Frog is the smallest true frog in Alberta, ranging from only 30-60 mm in length. Seen at Bentz Lake Natural Area on 6th August.
"Wood frogs tolerate the freezing of their blood and other tissues. Urea is accumulated in tissues in preparation for overwintering, and liver glycogen is converted in large quantities to glucose in response to internal ice formation. Both urea and glucose act as "cryoprotectants" to limit the amount of ice that forms and to reduce osmotic shrinkage of cells. Frogs can survive many freeze/thaw events during winter if not more than about 65% of the total body water freezes." From Wikipedia.
