Concept:Aestivation is a deep resting state that helps animals survive very hot, dry conditions.
Explanation:When an animal faces extreme heat and drought, it may enter aestivation to protect itself.
During aestivation, the animal becomes inactive and its metabolic rate is greatly reduced.
This lowered metabolism helps the body conserve water and energy until favourable conditions return.
Aestivation is different from hibernation, which is a winter response to cold temperatures.
It is an adaptation to arid and dry conditions rather than to cold.
The African lungfish and some snails show this behaviour during dry seasons.
This matches the description in the question best among the given options.
