This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Víbria (Catalan)
In and after the early Middle Ages, the European dragon is typically depicted as a large, fire-breathing, scaly, horned, lizard-like creature; the creature also has leathery, bat-like wings, four legs, and a long, muscular prehensile tail.
The Catalans also distinguish a víbria or vibra (cognate with English viper and wyvern), a female dragon-like creature with two prominent breasts, two claws, two wings and an eagle's beak. Dracs, Víbries and other mythological figures used to participate in correfocs during popular celebrations.
