Dragons come in many different colors, sizes and species. Generally they have four muscular limbs, powerful jaws, long tails, and huge wings.
The wings of a dragon can be scaly or leathery, depending on the species of dragon. A few have membranous wings, or wings made of metal. Its wings are used to fly great distances and heights, and can propel it into small crevices and openings. Like bees, it would be expected that dragons can't fly. But they have been able to build enough muscles to propel themselves through the air.
Most dragon claws can cut through just about anything, simply because absolutly nothing else that has been found is sharper than a dragon claw. They can have barbs and hooks to latch onto their prey, like porcupine quills, and some may use them to finish off their prey.
