Dragon

Dragons, family Draconidae, are a race of reptilian beings that are very diverse. They can range from the wingless Necrosian Fire Dragons and Longs to the clawless Ender Dragons, and more.

Biology
Dragons possess unusually lightened bones, some of which, namely the wing bones, are partially made of cartilage.

Members of the subfamily Draconicae possess bat-like wings, the membranes of which are usually composed of smooth, amphibian-like or mammal-like skin, or covered in denticles, instead of normal reptilian scales, which are only present on the parts of the wings that cover the bones; said scales are referred to as 'Wing scales' to differentiate them from the smooth skin or denticles on the membranes. The exception to this is D. e. naturae, which has a plant-like or amphibian-like dermis tinted with chlorophyll instead; however, the wing membranes may still appear as different colors. Members of Pterykaicheri possess wing-like structures on their arms, more akin to pterosaurs, but are distinguished from them by the remainder of their biology being more similar to other dragons' than to Pterosaurs. Members of Longidae lack wings, primarily using magic to fly and more rarely doing so.

Taxonomy
Draconidae is split up into four subfamilies: Pterykaicheri, or the Wyverns, contains only one genus; Longinae, or the Eastern Dragons, consists of one genus with two species; Draconicae, or the Western Dragons, is the largest subfamily, having four species: D. draco, D. elementum, D. amoria, and'' D. aether. Necrosinae is a wastebasket taxon, consisting of the species of Necrosian Dragons that cannot fit into other genera: the monophyletic genera Pyroraptor and Cetidraco.''
