Are Wyverns Dragons?
When people hear the word Dragon, they generally think of 2 different kinds: The long royal Asian Lung, or the 4 legged winged fire breathing beast of the west. But some rare dragons are more akin to Wyverns.
Wyverns are generally seen as 2 limbed, and winged. They are generally seen as not as intelligent as their other dragon cousin, though is not a given. Most family crests that are adorned with dragons with Western culture tend to contain wyverns.
So while many wyverns do not have names, they are sometimes the most commonly used in imagery!
So is the public image of a Dragon actually the most common one?
Wyverns
Wyverns are dragons that have two legs, and two wings. While not the most common, they can be found on European crests. In a modern world you'll see them in Peter Jackson's Hobbit series, or the dragons in Game of Thrones.
Serpents are basically nothing more than fantastical snakes. While this may not be what most modern people picture, most dragons in mythology are nothing more than great snakes. Take the Leviathan for example or Tiamat.
6-Limbed
A great creature with 4 limbs and 2 wings. What most people picture when they think of a traditional European dragon. And yet, traditionally this dragon is exceptionally rare. George's dragon is one of the few. In a modern world you'll see them in Dungeons and Dragons or Dragonheart.
