bat : any of a widely distributed order (Chiroptera) of nocturnal usually frugivorous or insectivorous flying mammals that have wings formed from four elongated digits of the forelimb covered by a cutaneous membrane and that have adequate visual capabilities but often rely on echolocation — Webster

Bats are mammals of the order Chiroptera; with their forelimbs adapted as wings, they are the only mammals naturally capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti’s hog-nosed bat, which is 29–34 mm (1.14–1.34 in) in length, 15 cm (5.91 in) across the wings and 2–2.6 g (0.07–0.09 oz) in mass. The largest bats are the flying foxes and the giant golden-crowned flying fox, Acerodon jubatus, which can weigh 1.6 kg (4 lb) and have a wingspan of 1.7 m (5 ft 7 in).
The second largest order of mammals, bats comprise about 20% of all classified mammal species worldwide, with over 1,200 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochiroptera, with megabats as members of the former along with several species of microbats. Many bats are insectivores, and most of the rest are frugivores (fruit-eaters). A few species feed on animals other than insects; for example, the vampire bats feed on blood. Most bats are nocturnal, and many roost in caves or other refuges. Bats are present throughout the world, with the exception of extremely cold regions. They are important in their ecosystems for pollinating flowers and dispersing seeds; many tropical plants depend entirely on bats for these services. — Wikipedia

A SARS-CoV-2 test for bats using fecal samples could boost understanding of how wild animals transmit viruses to other animals and humans.

Animals have three main strategies to survive the freezing temperatures of winter: migrating, remaining in place and resisting the cold, and reducing body temperature and metabolic rate in a state called torpor.
- Search reveals eight new sources of black hole...on May 2, 2022 at 4:40 pm
Scattered across our Milky Way galaxy are tens of millions of black holes—immensely strong gravitational wells of spacetime, from which infalling matter, and even light, can never escape. Black holes are dark by definition, except on the rare occasions when they feed. As a black hole pulls in gas and dust from an orbiting star, it can give off spectacular bursts of X-ray light that bounce and echo off the inspiraling gas, briefly illuminating a black hole's extreme surroundings.
- Hibernating bats have similar metabolism to that...on April 28, 2022 at 2:11 pm
A trio of researchers, two with Universidad Austral de Chile, and one with Universidad Católica de Chile, has found that a gram of hibernating bat has a similar metabolism to a gram of hibernating bear. In their paper published in Proceedings of the Royal Society B, Roberto Nespolo, Carlos Mejias and Francisco Bozinovic describe their work in scaling energy expenditures of multiple mammals to learn more about the benefits of hibernation in general.
- New study finds climate change could spark the...on April 28, 2022 at 9:00 am
As the earth's climate continues to warm, researchers predict wild animals will be forced to relocate their habitats—likely to regions with large human populations—dramatically increasing the risk of a viral jump to humans that could lead to the next pandemic.
