When Water Dragons mature, they lose the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

T'hetis is named for the silver-footed sea nymph in Greek mythology who is the mother of Achilleus.  As an elder of the nest, she is one of its leaders.  She does, indeed, have silver-webbed feet.  The trick is drawing close enough to her to view her webbed feet, for she never leaves the water and avoids human contact.
