What is it?

The olm is a long, pale-pink amphibian that lives in the cave waters of Slovenia. It's blind, breathes through feathery red gills on its head, and can live longer than almost any other amphibian on Earth.

Tell me more

Because olms live in pitch darkness, they don't need eyes - their skin is so pale you can almost see through it.

Instead of sight, they sense vibrations in the water and even pick up tiny electric fields from other animals.

Olms can go ten years without eating if they have to. They can live to be over 100 years old in the wild.
