A Flying squirrel
So they can catch the wind and glide when jumping from place to place.
To begin with, a flying squirrel does not have "featherless skin" as it is a mammal. It has skin without fur. Mammals do not have feathers. Secondly, the flaps of skin help these animals glide. Although they are called "flying squirrels", in reality they are "gliding squirrels". When they leap from a high point, they extend their forelegs and hind legs, spreading these skin membranes which then catch the air currents, allowing them to glide a short distance between tree branches. In this way, they can evade ground-dwelling predators more easily.
elephant have ear flaps so they can pick up good signal
Flaps of featherless skin between their front and back legs helps it fly better and faster

The cantle and the sweat flaps
Sugar Gliders are small marsupial animals that are usually found in Australia and surrounding islands. They have flaps of skin between their front and back legs, allowing them to briefly glide between one tree and another in their search of food, mates, and shelter.
Large ear flaps in some animals, such as elephants, are important for regulating body temperature. The blood vessels in the ears help dissipate heat, allowing the animal to cool down. Additionally, the ear flaps can help amplify sound for better hearing.
Splash cards are not as big as mud flaps and wont protect as well.

It is probably just what environment they have evolved to.
No, they glide why the flaps in-between their arms and legs!
