gliding
Quick Summary
Gliding is a form of animal locomotion that involves moving through the air without powered flight. Animals that glide, such as certain frogs, lizards, snakes, mammals, and birds, increase their body's surface area to enhance wind resistance and slow their descent.1
Adaptations for gliding vary:
* Frogs flatten their bodies and spread their limbs.1
* Snakes flatten their bodies and draw in ventral scales.1
* Lizards may have elongated ribs that fan out.1
* Mammals like flying squirrels and colugos possess a skin fold called a patagium, extending from the wrist to the ankle, which unfolds when they glide.1
Gravitational gliding can be directed towards a target or passive, acting like a parachute to slow descent. Some animals can control their glide direction by adjusting their body's surface area.23
