First,dragons aren't real.Second , if they were, some could, some may not bge able to.
Since dragons are fictional creatures, they can do whatever the writer of their story wants them to be able to do.
Oh, yeah!
They swim with the undulating motions of a snake. They don't do as well as an alligator or a crocodile but but better than a dog or anything that paddles.
All dragons can swim.I don't know of a dragon that has any difficulty in swimming but some are definitely better at it than others.Take it from an expert, the majority of us can swim more efficiently than any other creature. However, there are two types of dragons that can't handle swimming. Those that are single-element fire types of any species can't handle water well, but can still handle it well if they aren't single-element controllers. Also, Wyvern dragons tend to have a lotof trouble if they get their wings wet.
yes they do
swim
If you mean the Komodo, yes!
Yes they can.
No; they are far too dense to run across the water's surface. They can, however, swim quite well.
A True Dragon (Fire Drag) is capable of swimming, in much the same mode as a alligator, although only about half as well. They usually hold their wing up out of the water except when they dive in which case the hold them flat against their body. In burst of speed they will also thrash with their wings but this is not effecting, neither does it appear graceful.
No, but they can be together in the same place but they don't swim with each other.
No, Dragons do not excist
Bearded Dragons DO NOT need to swim ! They are a DESERT species - native to central desert area of AUSTRALIA ! The only time they need to be anywhere near water - is to drink !
