Dragons are legendary creatures, typically with serpentine or reptilian traits, that are featured in the myths of many cultures.
There are two distinct cultural traditions of dragons: the European dragon, derived from European folk traditions and ultimately related to Greek and Middle Eastern mythologies, and the Chinese dragon, with counterparts in Japan, Korea and other East Asian countries.
Dragons are usually shown in modern times with a body like a huge lizard or a snake with two pairs of lizard-like legs, and are able to emit fire from their mouths. The European dragon has bat-like wings growing from its back. A dragon-like creature with no front legs is known as a wyvern. Following discovery of how Pterosaur walked on the ground, some dragons have been portrayed without front legs and using the wings as front legs pterosaur-fashion when on the ground.
Although dragons occur in many legends around the world, different cultures have varying stories about monsters that have been grouped together under the dragon label. Some dragons are said to breathe fire or be poisonous. They are commonly portrayed as serpentine or reptilian, hatching from eggs and possessing typically scaly or feathered bodies. They are sometimes portrayed as having especially large eyes for watching treasure very diligently, a feature that is the origin of the word "dragon" (Greek drakeîn meaning "to see clearly"). Some myths portray them with a row of dorsal spines. European dragons are more often winged, while Chinese dragons resemble large snakes.
In the Disney Universe, dragons are usually anthropomorphic creatures themselves, or people magically turned into dragons.
