I read an magazine in the past where some frogs can be frozen solid, then thawed, and continue living.?

Question

is this true?

Answer 1

Yes, this is true. I'm pretty sure the particular species is the wood frog, but I'm not exactly sure.
In winter, the frog will "hibernate" and can freeze solid. Then once it gets warm, the frog thaws and continues its life.

If you want to test something like this, try using an earthworm. If you freeze a worm solid slowly, and then SLOWLY thaw it, the worm will still be alive.

The frog still has some brain activity when frozen, so it technically does not "come back to life". Currently, freezing things while keeping them alive is possible. Unfreezing, like the frog thawing, is beyond current technology.

Answer 2

Northern Wood Frog- and because of the important information gleaned studying the frog, surgeons can perform heart surgeries at a much more successful rate by cooling the body temperature of patients during surgery. By cooling the body, there is not as much damage done to major organ systems, during the crucial time of the heart not beating.

Answer 3

yes they have a chemical called glycerol that is liek a natural antifreeze. the only difference between this and being actually frozen, is that this chemical allows water to be frozen liek this at reduced temperatures, not the freezing point. however, once solid, you can then cool the frog into lower than freezing temperatures. yes this is true

Answer 4

I heard of one species of frog that, in the winter, they stop everything in their body, except their crucial parts, and get frozen. Then, when spring arrives, they get thawed and jump-start themselves and live. Is this what you meant?

Answer 5

yes, ive seen seen a video about it on the discovery channel =\, they can be frozen solid during cold weather, then they can thaw themselves out wih some sort of acid in there body=]

it was pretty neat.

Answer 6

Yes, several frogs, especially the wood frog, have been known to do this.

Answer 7

I actually watched a TV show on this a few weeks ago and yes, it worked. don't know why anyone would want to to it.

Answer 8

that is really sick... why would you wanna know about that?
