Is kermit going to be okay? I've always wondered how frogs, fish and bugs survive the winter

Frogs hibernate in water or underground, fish live under the ice, and bugs migrate, hibernate, or lay larva and eggs.

According to the last article, the frogs Chiruno freezes could actually live even though frozen:
>ice crystals form in such places as the body cavity and bladder and under the skin, but a high concentration of glucose in the frog's vital organs prevents freezing. A partially frozen frog will stop breathing, and its heart will stop beating. It will appear quite dead. But when the hibernaculum warms up above freezing, the frog's frozen portions will thaw, and its heart and lungs resume activity

how can animals sleep several months without being hunted

I thought the reason humans couldn't get cryogenicized is because cells explode when they freeze because of biology science? I wish they had explained it in hataraku saibou because then maybe an idiot like me could understand it...

You're basically right as far as I know. Most animal cells contain water and are encapsulated by only a thin cell membrane. When the water freezes, it expands and crystalizes. This causes the cell to burst. Rigid cell walls like the ones found in plant cells or bacteria can potentially help the cell survive as can "antifreeze" molecules dissolved in the cellular fluid as mentioned above (think of the way salt water can get below freezing temps without turning to ice). Some creatures can also dehydrate themselves to keep from freezing like the microscopic waterbear.

Apparently the opposite happens to frogs, their cells shrink because water is drawn out.

>Both urea and glucose act as cryoprotectants to limit the amount of ice that forms and to reduce osmotic shrinkage of cells.

its nice to know i wasnt completely wrong
