Where The 'Human Fish’ Dwells

The proteus or olm aka the "human fish" is an eel-like amphibian that can live for more than 100 years, survive 14 years without food, and dwells in the Postojna Caves in Slovenia.

The proteus is something of an icon in Slovenia, even appearing on coins before the arrival of the euro. Hundreds of years ago, when floods occasionally washed the creatures from the region's caves, they were regarded suspiciously as baby dragons.
