Detailed explanation-1: -Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months.

Detailed explanation-2: -Estivation is when animals slow their activity for the hot, dry summer months. During a period of estivation, many reptiles go underground where it’s cooler. Estivation is very similar to hibernation, when some mammals spend the winter moving very little and sleeping a lot, in order to save energy.

Detailed explanation-3: -Estivation is summer dormancy, that is, long-term torpor during summer for survival of hot and dry periods. Many desert plants survive extended periods of high temperature and low rainfall. Some survive as desiccated seeds (5%–10% water content), particularly annual species, but some survive desiccation as adults.

Detailed explanation-4: -Estivation is when animals are dormant because weather conditions are very hot and dry. Their breathing rate, heart rate and metabolic rate decrease to conserve energy under these harsh conditions. These animals will find a spot to stay cool and shaded.

Detailed explanation-5: -A few animals on this list include: the Water-Holding Frog, the Desert Tortoise, and the African Lungfish. Estivation refers to a dormant state where the animal’s metabolism is reduced, humans estivate during the winters months as well as some of these animals. Snails and crocodiles are also known to estivate.
