[edit] Draco odiosus fabulosus

The Gorgon is a large seagoing dracoform that barely resembles any of the other known dragons. It's long gilled neck, surrounded by a crowning ring of appendages and lack of any wings marks this creature as very different. Since none have ever been captured, and only a single specimen was ever made available for dissection, not much is known of these creatures and any degrees of sentience remain undiscovered.
