"Delta" is part of a species thought to be long extinct since the time of the dinosaurs. Like a typical dragon, it can run and fly, as well as swim exceptionally well. "Fluffy" parts of head are feathered, and back and tail have sharp spine-like feathers. Their diet is primarily aquatic flora (both marine and freshwater). Collects things, mostly gemstones, fossils, and colorful relics mistaken for these treasures. Mated to Lota.
*A Dino/Dragon species I made up in second grade called, and I kid you not, a bubbleshmakybooplong-kellomatoshoospinechromosomomackashakoolakosh and I don't know why I still remember that.
