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 ]
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 ...
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.”
Each individual will have similar immune systems, as immune systems are genetically based. When a species becomes endangered, the population may fall below a minimum whereby the forced interbreeding between the remaining animals will result in extinction. Natural breedings include inbreeding by necessity, and most animals only migrate when ...
Once the babies are slightly larger, the mother will begin leaving the nest for short periods of time to bathe and hunt for herself. During this time, the father stays near the nest in order to ...
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.
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.
