Dragon

Dragon is the common name for a member of a class Draconia within Verbebrata; one of 6 classes within that group, alongside mammals, birds, reptiles, amphibians and fish. Dragons split off from the same ancestors as birds and reptiles millions of years ago, and are considered a "missing link" due to possessing both the scales of reptiles and the flight ability of birds. Several dragon species are also extremely resilient to things that would poison other animals.

In popular culture

 * Several dragon species are used as heraldic symbols; for example, a greater Welsh red dragon represents Wales (despite the species being quite common in the western parts of the northern hemisphere as a whole, as far west as El Kadsre, as far east as the Balkans, and as far south as French Guyana), and a common Asiatic dragon represents China.
