Predators prevent some of the eggs and tadpoles from developing. Nevertheless, in the strictest sense the designation fails because the cessation of body functions is entirely and spontaneously reversible. Active cells need oxygen and other nutrients from the blood and must send their waste substances into the blood. The glucose molecules are used as an energy source. Hi Linda, I found this article quite intriguing.,,,,,,,,,, If this is your first visit, be sure to Not as bad as when I step on big snail. You will receive a verification email shortly.

I can imagine why you are fascinated by this little creature. Is there something about the frog's anatomy that allows it to do this? As a result, a hibernating frog looks as though it's frozen and feels like a solid block. Q: Hi, Jon. The nucleating agents include certain minerals and bacteria that the frog has ingested as well as specific proteins in its body. Thanks so much.

The temperature of ectothermic organisms is generally the same as that of the environment. The frozen liquid includes the blood. Louise Powles from Norfolk, England on March 20, 2017: Goodness, I had no idea about wood frogs. the internet is full of lies, just askyermom.

I was wondering if the same mechanism is possible in human beings? These factors may damage the area. Costanzo: There is a minimum survival temperature for wood frogs and all other freeze-tolerant animals. I appreciate it very much. I wrote this for one of my kids who was distressed about having stepped on a frog. Will our solar system survive the death of our sun? As the wood frog is freezing, its heart continues pumping the protective glucose around its body, but the frog’s heart slows and eventually stops. Although the water in the frog's cells doesn't freeze, at least some of the water outside the cells does. Researchers are still studying this and the mechanisms that protect the frog, aside from glucose. I’ve read reports saying that wood frogs in the lab can go through multiple freeze-thaw cycles if the environment gets cold enough to trigger. This amazing animal survives months of hibernation with much of its body frozen and without a beating heart.

Good Job ! Jeanne. I never knew that frogs actually mated. Other desert inhabitants use external water storage tanks – in the form of the water-holding frogs.

Why this particular answer gets so much traffic is a real mystery…, Yeah probably dozens and dozens barefoot the apartment complex I lived in had a large pond between my apartment the laundry room and the rec center where yoga classes were held, seeing as how you don’t where shoes doing yoga I would walk there barefoot during heavy rains the frogs would be hopping about and with the area being poorly lit it was a regular occurrence stepping on them barefoot a little gross at first but after the first few it wasn’t that bad the other person was correct they really to go splat and squirt between your toes, but its not really that bad far more would’ve been flattened if I drove my car over there instead, so I guess I was probably doing the frogs a favor by stepping on them instead . Q: How durable are these frogs in the frozen state? In fact, if you opened up a frozen frog, the organs would look like "beef jerky" and the frozen water around the organs like a "snow cone," says Jon Costanzo, a physiological ecologist at Miami University in Ohio who studies freeze-tolerance.
