Bats are the only freely flying mammals. [59] A few other mammals can glide or parachute; the best known are flying squirrels and flying lemurs. Flying squirrels (subfamily Petauristinae). There are more than 40 living species divided between 14 genera of flying squirrel.
Flying squirrels can glide long distances by increasing their aerial speed and increasing their lift. [5] Other hypotheses state that the mechanism evolved to avoid nearby predators and prevent injuries. If a dangerous situation arises on a specific tree, flying squirrels can glide to another, and thereby typically escape the previous danger.
Colugos are proficient gliders, and thought better adapted for flight than any other gliding mammal. They can travel as far as 70 m (230 ft) from one tree to another without losing much altitude, [10] with a Malayan colugo (Galeopterus variegatus) individual having been observed traveling about 150 m (490 ft) in one glide. [11]
To assist gliding, some mammals have evolved a structure called the patagium. This is a membranous structure found stretched between a range of body parts. It is most highly developed in bats. For similar reasons to birds, bats can glide efficiently. In bats, the skin forming the surface of the wing is an extension of the skin of the abdomen ...
The sugar glider (Petaurus breviceps) is a small, omnivorous, arboreal, and nocturnal gliding possum.The common name refers to its predilection for sugary foods such as sap and nectar and its ability to glide through the air, much like a flying squirrel. [8]
Blood flow in the toes of wandering salamanders helps them to glide over the tops of redwood trees. ... More research is needed to understand how it works to serve those species in their habitats.
The three species of sanguinivorous bats belong to the subfamily Desmodontinae. These bats are characterized by relatively high wing-loading and short or average wingspans. [ 27 ] The high wing-loading allows them faster flight speeds, which is advantageous when they have to commute long distances from their roosts to find prey. [ 27 ]
German company Vosschemie produces a hull paint called Haifischhaut, which reduces the drag effect and allows ships to glide more easily through the water. Image credits: Nigel Mander #11 Robotic Arm
