Freezing North American Wood Frogs

Frogs have always facinated me. Back in 1982 in my Biology class we were forced to dissect frogs. One of my best friends was my partner and the dissecting fell upon me. Frog biology was one of beautiful design. Over the years, I would marvel at pictures of frogs around the world and take trips to creeks and ponds to watch tadpoles.
I found a video about North American Wood Frogs who can literally freeze up, stop breathing, heart stops, and everything only to be thawed and awakened to mate.Science doesn't know what   This is exhibit #156 among thousands of reasons that we ought to save them. The things we do to save them can also save the planet.
