Preparing for take off!
The dragon tucks its wings in and propels itself off the tree using its limbs to accelerate. Unlike fighter jet engines, the rapid acceleration is provided by the limbs and the streamlined body which takes the form of a stick to minimize drag. As it dives, it exploits gravity to gain enough speed before flaring up its wings to create and control aerodynamic forces!
Another example of how lizards modify their body shape to manipulate air flow!

Gliding animals are not paper planes - and yet many studies have modeled them so. Flying lizards are agile gliders with a unique wing design, capable of active control over their glide path. Past research has studied lizard glides in 2D, which cannot capture details like body shape and orientation. I will track body points in 3D during the glide along with morphometric measurements, which will lead to more realistic models and give insights into gliding biomechanics of these animals.
