Is There a Difference Between Dragons and Dragons?

Wyverns are desoina wings on hea. Wivens are like, almost identical to dragons, except what is at they don't breathe fire and they're smaller. And a lot of times they n their behavior little difernt. So so maybe maybe the dragons in e t maybe we don't hear about them so much because they're more secretive. They keep to themselves. I know maybetimes as wellbut they could actually also be physically different.
