They will lightly cover themselves with mud at the bottom of the pond to escape being seen by predators. Many frog species choose to remain in the water during hibernation. The heart and lungs will amazingly start working again, and the frog actually comes back to life. The frog’s metabolic rate will begin to slow in response to cold temperatures, and it must find a place to wait out the winter before it freezes. They do not bury themselves in the muds of these systems. Once the weather gets warmer, the frog will begin to thaw out. Aquatic frogs (like the leopard frog (Rana pipens) and the American bullfrog (Lithobates catesbeianus) and the northern green frog when it decides to overwinter in a body of water) spend the winter if not frozen then nearly so in the still liquid environment of their ponds or pools. 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. 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. 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. 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. Although most UK amphibians will hibernate on land, examples of both frogs and newts have been found to bury themselves in the silt at the bottom of the pond. Do pond frogs die the winter Aquatic frogs usually hibernate underwater and they usually spend the winter at the bottom of a. Other frogs will burrow deep below the frost line in burrows or cavities called hibernacula, or hibernating spaces. 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. Some frogs spend the winter swimming slowly under the ice and in the water of ponds, lakes and streams. 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.
