I already know that fish and frogs can be frozen, and Iv'e frozen about a dozen caterpillars and they've been revived.

Fish have been partially frozen and revive on their own. Scientist have revived small rodents after being frozen in ice ... BUT ... these were under special cases. In a lab with close monitoring and with special equipment.
The problem with freezing something solid is that the cell structure is typically destroyed when an ice crystal forms inside the cell it ruptures the cell wall. The cell is then dead and while it holds its shape ... like a piece of frozen meat, it is dead.
The way the scientist got around the cells bursting is with special chemicals and or increased atmospheric chamber. Something I would not suggest for any human ... or even a pet :) (Like the stunts on TV do not attempt at home).
One more thing - people have been revived as much as 40min after falling into icy water, but the cells are not actually freezing solid. Hope this helps and please do not freeze any pets - leave that to the pros :) MAC

There are a few animals that can go into suspended animation and be frozen. The cockroach is an infamous example. but there are also a few insects in secluded and frozen areas that can do the same. They freeze up almost completely during the winter and thaw after winter's over. If humans do that, their tissues and cells would be effected...we all know what a frostbite is. The cells in the body would die. Some times people get lucky and go into states of coma or something similar where only their hearts and brains function. that way the rest of the body slowly dies off and leaves the heart and brain alive waiting to hopefully thaw.

There's research going on as to freezing people for operations, for research and probably for fun. but nothings for certain. Just dont try it at home.

i dont know about being frozen solid in ice but a few years back a child was frozen in a pond ans was brain dead without a pulse but somehow was revived and is now healthy, and there has been research after that episode into reviving frozen people , and there are a few more cases like that one, but i am just shoting from the hip right now

Well the Wood frog of the United states (Rana sylvatica). It has adapted to winter in North America by developing Cryoproteins in its blood that allow it to freeze solid, but not to the point of cell lysis, basically the water in its blood never forms crystals, these would certainly cause the cells to rupture, killing the animal. They are the only frog species that can be found north of the tree line in the canadian Boreal forest. They can freeze and thaw several times a season if the weather tells them to, they will basically just walk until they freeze, then revivie, and do the same over again if the weather fluctuates. I attached a photo of these frogs, they are pretty cool and are actually quite common .
I hope this answers your question!

Water expands when it freezes. Since all living cells contain water, freezing causes them to burst so, in short, no. Humans cannot currently be revived after being totally frozen.

If you don't believe me, stick a flower in the freezer and leave it there overnight. Take it out and let it thaw the next morning and see what happens.

Other than Captain America, I don't know any other beings who can be revived after being frozen in ice.

Cockroaches can survive being frozen for months. Currently, humans cannot.

i dunno what animal.....but i know that human cannot be revived after bieng frozen in ice because so of of cells and tissues will be damaged when it is cold.it cannot be repaired anymore.therefore human cannot be revived after being frozonin ice.thank you...
