![]() ![]() Animals that bruminate will find a habitat that is safe and warm to stay inactive. Frogs and other ectotherms rely on their environment to provide them with heat rather than their blood. Although they will accumulate ice crystals inside their small bodies and stop breathing, they will awaken as soon as the temperature warms and their bodies begin to defrost. Brumation Brumation is the same as hibernation but for cold-blooded animals ( ectotherms) such as amphibians and reptiles. While estivation is a common survival strategy for frogs that live in extremely dry climates, it is also an effective tactic for winter survival.įrequently Asked Questions about Where Frogs Go in the Winter If you come across a frog in the wild that is inhabiting a pond less than 16 inches (40 cm) deep, the water may freeze all the way through due to its shallow depth. When estivating, frogs will shed their skin to mummify themselves inside of a homemade cocoon, which protects them from severe weather conditions.Īfter the climate is once again suitable for life, they will go back into their natural habitats. When aquatic frogs begin to hibernate in October, they usually need a lake or pond deep enough to escape the frozen surface. While most Northern American frogs hibernate through the winter, there are some species of frogs, indigenous to harsher climates, that engage in a process referred to as estivation in response to extreme weather conditions.įor instance, the African Bullfrog is known for estivation throughout seasons of hot, dry weather. While they usually remain still for the duration of winter, they may occasionally swim around a little before returning to their chosen place on top of the mud. Instead of breathing during hibernation, aquatic frogs survive by the water’s oxygen content naturally seeping through their bodies. Well, aquatic frogs need to seek out a source of water that has a rich supply of oxygen to carry them through the winter. But ponds are typically low in dissolved oxygen, so many freshwater insects breathe air and can fly between ponds. Sure, frogs and tadpoles have gills, but that’s an awful long time to stay underwater! Some creatures spend their whole lives submerged in a pond, such as freshwater hoglice that have gills to aid their aquatic lifestyle. Some scientists prefer the term brumation, to indicate that the animals simply enter a period of low metabolic function and activity, but not in the way that mammals overwinter in a very deep sleep. Now, this may leave you wondering how the frogs manage to breathe while they spend several months relaxing at the bottom of a pond. Indeed, hibernate may be a slightly misleading term. Instead of burrowing deeply underneath the mud at the bottom of a lake, as turtles are known to do, aquatic frogs will lie directly on top of the mud to avoid suffocation. ![]() Aquatic Frogs Hibernate in the Water Throughout the WinterĪquatic frogs, such as the American Bullfrog, also have interesting hibernation tactics, but their exact technique of underwater winter survival may be slightly surprising.
