Questions related to Hibernation and Aestivation were asked in CTET 2022, so you should be aware of it. You will be asked the question that which of these animals hibernate or which of these animals do not hibernate? So such questions become important for the upcoming CTET exams. Apart from this, the topic aestivation related to it can also be important because it is possible that in the upcoming examinations questions will be asked from aestivation.

Difference between hibernation and aestivation
If you observe some animals around you carefully, you will come to know that they are not visible for some time throughout the year, such as lizards, frogs, moles etc. You will not see lizard in winter, similarly you see frog mostly in rain. Have you ever thought that when these creatures are not visible then where do they reside at that time? The answer is hibernation.
Only cold blooded animals go into hibernation because these animals cannot tolerate low temperature, so before the cold comes, they go to a place where their body can bear the temperature. For example, a lizard will hide in a crack of a wall, a snake will enter a burrow under the ground, a squirrel will hide in a hollow of a tree.
Example of hybernating animals
Turtle, Snake, Bear, Lizard, Shrew, Fish, Squirrel, Bat, Frog, Snail etc.
Hibernation and aestivation or Estivation both are almost same process but the objectives of both of them are different and the duration of both of them is also different. In Aestivation, cold blooded animals rest for a short time on a wet place or in a shady place when the temperature becomes very high during summer.
The objective of both hibernation and aestivation is to maintain body temperature, but the reason for hibernation is low atmospheric temperature and the reason for aestivation is high atmospheric temperature.
Example of Estivating Animals
Frog , tortoise, Snails, squirrel, Earthworms, Reptiles , Amphibian etc.
