The wood frog has evolved traits that prevent their cells from being damaged when frozen and thawed out. The wood frog has developed various adaptations that allow it to effectively combat prolonged ischemia/anoxia and extreme cellular dehydration. One crucial mechanism utilized by the wood frog is the accumulation of high amounts of glucose ...
Moor frogs are renowned for their ability to tolerate freezing temperatures because most frog species live in hot and humid tropical environments. Many frogs that do live in cold climates will attempt to overwinter in bodies of water because ambient temperatures are moderated by water. In these cases, temperatures only reach a few degrees below ...
Some frogs such as the wood frog, moor frog, or spring peeper can even survive being frozen. Ice crystals form under the skin and in the body cavity but the essential organs are protected from freezing by a high concentration of glucose. An apparently lifeless, frozen frog can resume respiration and its heartbeat can restart when conditions ...
But somehow, the frogs survive. Further research on the species could provide useful clues for the development of anti-blood clotting medications, said Carlos Taboada, a Duke University biologist ...
The spring peeper is a tan or brown frog with a dark cross on its dorsa (thus the Latin name crucifer, meaning cross-bearer [7]), though sometimes the marking may be indistinct. [ 8 ] [ 9 ] Dark lines can also be found between the eyes and in a crossband on the hindlimbs of P. crucifer . [ 10 ]
Some cryoprotective agents used in research are inspired by plants and animals in nature that have unique cold tolerance to survive harsh winters, including: trees, [3] [4] wood frogs, [5] and tardigrades. [6] The first human corpse to be frozen with the hope of future resurrection was James Bedford's, a few hours after his cancer-caused death ...
