Olms are underwater cave-dwelling salamanders found in Europe.
The neatest part about these unique, entirely aquatic amphibians is that they have long bodies, heads, and no eyes, unlike their relatives of axolotls.
They also can live up to a century and go a decade without food due to their low metabolism.
In Slovenian folklore, the olm is considered a baby cave dragon, as they would wash up from the underground after a heavy downpour.
