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.
What is Estivation in biology?
Definition of estivation 1 zoology : the state or condition of torpidity or dormancy induced by the heat and dryness of summer : the state of one that is estivating Some animals, including various species of snakes, land snails, and lizards, enter a state of dormancy, or estivation, in the summer when water is scarce.—

Human hibernation doesn’t exist for many reasons, but the reason why is not quite as immediately obvious as you might think. Hibernation is a response to cold weather and reduced food availability. Humans don’t hibernate for two reasons.
What is Estivation in an amphibian?
When amphibians estivate, their breathing, heart rate, and metabolic processes such as digestion all dramatically slow down. This decreases the organism’s need for water. Some frogs and salamanders form a mucus cocoon around themselves to prevent water loss through their skin.
What is Estivation in plants?
Aestivation or estivation is the positional arrangement of the parts of a flower within a flower bud before it has opened. Aestivation is also sometimes referred to as praefoliation or prefoliation, but these terms may also mean vernation: the arrangement of leaves within a vegetative bud.
