Draco Berengarius

Draco Berengarius is a species of animal that is found on Berengaria VII. It is a class Q species.

When he was living on Berengaria, Elias Vaughn was once attacked by one of the creatures. The creature penetrated into the back of Vaughn's skull, causing some slight brain damage and leaving behind its own DNA traces. Vaughn would be left with a scar running from his neck to above his left ear. (DS9 novel: Bajor: Fragments and Omens)
