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 ]
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.
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 ...
Meeting an exotic animal at a public attraction can fill us with wonder, but critics say that this can also be dangerous. Dana Garber said she had just such an encounter at the Endangered Ark ...

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.” ... some animals can have ...
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 ...
The reason why some researchers are skeptical about animals having a sense of humor is that it serves no evolutionary purpose. For humans, it's a bonding strategy. For humans, it's a bonding strategy.
