There are many possible answers to this question and you may choose the one you feel most comfortable with.
- They croak
- They hop it to somewhere warmer
- Saint-Tropez
- My throat
- A-courting
- Aquatic frogs submerge themselves and absorb oxygen from the water through their skin. Other frogs will bury themselves in leaves and mud to protect themselves from the worst conditions and hibernate until warmer months
- They involve themselves in a lengthy joke with a chicken that borrows books from a library
Any and some but certainly not all of the above may prove helpful.
If you want a serious answer, there are two of them: some bury themselves in the bottom of water bodies that don’t freeze to the bottom and slow their metabolism to nearly nothing, taking up oxygen through the skin. Others, like the Wood frog (Lithobates silvatica) and Grey Tree Frog (Hyla versicolor) actually stay on the surface an allow themselves to freeze, using concentrations of glucose and ice nucleating proteins to regulate where crystals form. They stay that way, heart, lungs, everything frozen until spring, when they thaw, remarkably, from the inside out. Biologists are still trying to sort out how that happens.
And with the addition of comments of this quality, this site becomes (as it was always hoped to be) a nice mix mix of the frivolous and the factual.
I’m glad I could help.
Thanks Heather, although I liked the tongue in cheek comments, your answer was what I hoped to find out.
