Doena

They are dragons that disguise themselves in lakes and ponds, striking at their prey out of seemingly nowhere. Their manes can pass for grasses and they often let algae, waterplants, mosses, ferns etc grow on their scales.

Kelpies usually just, if they feel the need to, glide as water tends to soak into their feathers and manes making proper flight hard, unless they let their wings and mane dry completely.

Selected dragons of the right size, coloring and patience with hatchlings (usually imperials or guardians), even lie down in dips of the land, doubling as an entire pond or lake, and sometimes you could only tell these 'ponds' apart from dragons by touching.
Those dragons usually are the ones assigned to disguise and protect groups of nests and hatchlings while smaller adults take care of them, but are also known to use this tactic for hunting if pressed for food.

You will occasionally see confused ducks or geese sitting on these dragons!
