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.

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.
This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs.
A boa constrictor in the U.K. gave birth to 14 babies — without a mate. The process is called parthenogenesis, from the Greek words for “virgin” and “birth.”
Many xerocoles, especially rodents, estivate in the summer, becoming more dormant. [5] Some desert amphibians estivate underground for over a year at a time. [10] Unlike hibernation, which leads to a state of torpor, estivation induces lethargy, and can go unnoticed in some animals if their body temperature is not measured. [13]
A Memphis Reddit user asked "what has gotten better in Memphis over the last 20 years.' The overwhelming response shows why we love the Bluff City.
It has been observed in animals ranging from rodents to primates, and even in some instances humans. The most extensive study has been on animals in orders Rodentia, Chiroptera, Lagomorpha, Carnivora, Perissodactyla, Artiodactyla, and Primates. [2] Exceptions to the ubiquitous behaviour in mammals can be seen in humans, sea mammals and camelids ...
