If you freeze a frog...and then put it in warm water?

This works with only specific frogs, like the common wood frog. (But it was never dead, so it didn’t exactly come back to life…)

I ask my science teacher this question about a fish and she said no…. But I do know that they freeze humans and replace their heart when they do open heart surgery

Good question. I always wonder about eggs and sperm. How is it possible?

The don’t freeze them, iCeskate, they chill them to slow metabolic and physiological changes.

When the water in cells freeze they cause massive damage to the cells just like if you froze a jar of water and had the expansion crack the glass. This is the big hurdle that cryogenics is having trying to freeze people right after they die so that they can be thawed out and revived some day in the future when medical technology has improved. At least that is my understanding of the situation. I’d be interested to hear how those certain species of frogs are able to be frozen without their cells being damaged, sounds interesting.

@gorillapaws The articles that I’ve read merely refer to a “natural antifreeze” in their blood and tissues that allow the cells to freeze without rupturing the cell walls or damage organelles. I suppose they never expound on the “natural antifreeze” because they don’t know how it works. “Winter World: The Ingenuity of Animal Survival” goes into a great amount of detail about hibernation and its alternatives.

Why would you want to freeze a frog? Poor froggies!
Ribit! Brrr!!!

Actualy, gorillapaws and syz: The video actually talks about that. Its in my first comment. The link to it is, at least. :)

Walt Disney comes to mind
