The heart and lungs will amazingly start working again, and the frog actually comes back to life. Once the weather gets warmer, the frog will begin to thaw out. Moor frogs are known for their ability to freeze. The term “winter kill” occurs when a frog is tempted out of its hibernating spot by an early warm stretch followed by a quick drop in temperatures below freezing. The moor frog (Rana arvalis) is a slim, reddish-brown, semiaquatic amphibian native to Europe and Asia. If the frog emerges too soon, it can result in tragedy and death. However, if it does get too cold, the frog can die. A high concentration of glucose or sugar in the frog's vital organs inhibits freezing and without this physical process, the ice crystals would damage tissue and result in the frog’s death.Īs much as 70 percent of the water in a frog’s body can be frozen. So why doesn’t the frog die?ĭuring this period, the liver produces large amounts of glucose to increase blood-sugar levels, which functions like a natural “antifreeze” by limiting the formation of ice crystals in the body. Proper pet care needs will change from what you need as far as tank set-up to what type of food you will need. Some frogs need to hibernate during the winter, while others do not. Frogs go as deep as they can or squeeze into cavities, crevices, and logs.Ī partially frozen or frozen frog will stop breathing, and its heart will even stop beating and it will appear dead. There are many species of frogs, and many of them have very individualized pet care needs. During the winter, they go into a state of hibernation, and some frogs can be exposed to temperatures below freezing.įrogs and toads that spend most of their time out of the water and on land can usually burrow down below the frost line in burrows or cavities that are their hibernating space for the winter. These types of frogs sometimes even slowly swim or move around during the winter.Īs mentioned above, frogs and toads are cold-blooded, so their body temperature actually takes on the temperature of the environment around them. Aquatic frogs usually hibernate underwater and they usually spend the winter at the bottom of a pond or other body of water.įrogs don’t burrow down into the mud to hibernate though they can be found hanging out on the bottom just above the mud. However, adult toads hibernate during nonbreeding season (March-August) making it very hard to find them in nature (Gallardo, 1958). Winter does present a major problem for frogs because it’s too cold for them to be active, so they need to find somewhere to wait it out. Frogs can sometimes freeze solid during the winter, but usually don't die.During the winter, frogs go into a state of hibernation.Frogs and toads are cold-blooded creatures.
