Tiny dragon discovered in Indonesia



Tiny dragon discovered in Indonesia


Draco volans, or the Flying Dragon, is a member of the genus of gliding lizards Draco. It can spread out folds of skin attached to its movable ribs to form “wings” that it uses to glide from tree to tree over distances upwards of 8 metres (25 feet); however, like all modern reptiles, it lacks the ability to sustain powered flight, and is capable only of gliding. Its wings are brightly coloured with orange, red and blue spots and stripes, and they provide camouflage when folded. The flying dragon can reach lengths as long as 19 - 23 cm. It feeds on arboreal ants and termites.
Yeah, that’s my cute overdose for the day…
The “discovered” thing is a bit misleading, since those things were scientifically described in 1758.
But I love how many different ways wings (and gliding surfaces) have evolved. Bird wings are a condensed hand and bat wings are a spread hand. Flying-fish wings are fins and flying-squirrel wings are stretched between their limbs. Bug wings are exoskeleton and flying snakes use their whole body to glide. Human wings are made through our aptitude for technology. And this little critter has made wings out of RIBS.
Nature is so awesome.
