Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs . The practice has been observed in many species throughout the animal kingdom, especially primates ( primate infanticide ) but including microscopic rotifers , insects , fish , amphibians , birds and mammals .

Aestivation, also spelled estivation, is an example of consequential dormancy in response to very hot or dry conditions. It is common in invertebrates such as the garden snail and worm but also occurs in other animals such as lungfish, salamanders, desert tortoises, and crocodiles.
The hatching of the 107th tiny, wriggling snake at a Tennessee zoo marks the end of another year of efforts to save one of North America’s rarest snakes from extinction.

Two young Tennessee children died Wednesday after they were attacked by two family dogs, the Shelby County Sheriff’s Office said. Their mother was also injured in the attack north of Memphis ...
The larval stage of insect development is considered by some to be a form of altricial development, but it more accurately depicts, especially amongst eusocial animals, an independent phase of development, as the larvae of bees, ants, and many arachnids are completely physically different from their developed forms, and the pre-pupal stages of ...
Male Canadian garter snakes huddle around a female after hibernation when mating.. Huddling confers higher and more constant body temperatures than solitary resting. [3] Some species of ectotherms including lizards [4] and snakes, such as boa constrictors [5] and tiger snakes, [6] increase their effective mass by clustering tightly together.
