The wood frog...
fascinating creature
Wood Frog is the common name given to Rana sylvatica. They are the only frogs found north of the Arctic Circle. Wood Frogs have the special ability to freeze their bodies. In the winter, as much as 35-45% of the frog's body may freeze, and turn to ice. Ice crystals form beneath the skin and become interspersed among the body's skeletal muscles. During the freeze the frog's breathing, blood flow, and heart beat cease. Freezing is made possible by specialized proteins, glucose and perhaps accumulation of urea, which prevent intracellular freezing and dehydration. Wood Frogs tend to stay in the same area. They generally occupy an area of about 1000 square feet (100 mhahaha178;).
