Dragons are legendary creatures, typically with serpentine or otherwise reptilian traits, that feature 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 Asian countries. The two traditions may have evolved separately, but have influenced each to a certain extent, particularly with the cross-cultural contact of recent centuries. Dragons are usually shown in modern times with a body like a huge lizard, or a snake with two pairs of lizard-type legs, and able to emit fire from their mouths. The European dragon has bat-type wings growing from its back. A dragon-like creature with no front legs is known as a wyvern. Following discovery of how pterosaurs 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.
