Hibernation; When the weather starts to get colder, the “cold-blooded” frog retreats to its nest and goes into a deep hibernation.
Frogs do not need to make any preparations for winter, neither to think about winter nor to order firewood.
Once the temperature drops below zero degrees, the frog’s metabolism spontaneously slows down and is completely dormant except for a few short warm winter days from November to March.
When the weather gets even colder, frogs move their nests from damp places by lakes to dead areas of tree stumps or among fallen leaves.
Because they are cold-blooded animals and their body temperature is related to the outside temperature. The reaction of many different frog species to the weather is different according to the climate of the places where they are settled.
All species have noticeably reduced respiration, some submerge almost completely and breathe only with the aid of their skin.
The water content of their tissues decreases and the blood becomes more concentrated. These amphibians (both terrestrial and aquatic) include reptiles, birds, and mammals.
For example, they cannot survive at -1 degrees. Therefore, they are not found in very northern or southern climates.
All cold-blooded hibernators are in danger of freezing if ice crystals form in their plasma that kill cells and tissues.
The green tree frog usually lives in warm climates where winters are quite short. Temperature has also been shown to affect the sexual development of frog eggs dramatically.
Cold Blooded – Warm Blooded
At +10 degrees, a large number of females are formed, on the other hand, at +27 degrees, the majority of them are males.
Hibernation means either the inactivity of cold-blooded animals or the body temperature of warm-blooded vertebrates falling to 0 degrees and their metabolism slowing down.
For example, bears’ temperatures drop by only a few degrees. Warm-blooded animals that go into hibernation can always wake up from their sleep, unlike cold animals.
A herpetologist (a specialist in crawling animals) is of the opinion that being cool-headed has its own advantages.
Frogs, for example, are content with much less food during their active phase because they do not need to burn off food energy to stay warm.
