Cave olms never grow up: they spend their entire lives in the larval stage. Researchers estimate that they can live to be 100 years old. The females are sexually mature at around 15 years of age and then reproduce about every twelve years.
The cave olm can survive for up to 10 years without food.
As the cave olm only lives in the absolute darkness of caves, it has no eyes and pigmentless, transparent and pale pink skin through which the blood vessels and organs are clearly visible.

The olm is a European tailed amphibian that lives permanently in larval form in cave waters and is the only species of the genus Proteus. This genus, together with the North American furrowed newts, forms the olme family.
