Water dragons are, presumably, dragon-like magical creatures that inhabit bodies of water. They usually carry a specific kind of parasite that can also be transmitted to humans, infecting their tear ducts.
In 1927, Newton Scamander speculated that there might be a water dragon living in the Parisian sewer used by Yusuf Kama as an hideout, after discovering (and later successfully extracting) a water dragon parasite in the latter's eyes.
Behind the scenes
- Physignathus are a real-life genus of lizards commonly known as water dragons. However, they are native to Southeast Asia and Australia, not Europe, making them unlikely candidates for the creature mentioned in Fantastic Beasts: The Crimes of Grindelwald. Alternatively, in real-life, the term water dragon can also refer to Saururus cernuus, a plant native to eastern North America.
