Olm Diary

In 2016 the whole world was excited to witness a remarkable event. This is the story of the incredible development of our "baby dragons" from eggs to 8-month-old juveniles.


DAY 01

Cave guide Juan Pablo Maschio noticed the first olm egg and informed Postojna Cave management and scientists who work there. All other olms, which could disturb the egg-laying process or even eat the eggs, were removed from the aquarium, with only the dragon mum and her egg left in it.

Did you know?

The pregnant female olm is fiercely defending her eggs from the other olms.


DAY 05

A new egg was spotted in the aquarium. In the last three days, the female olm relocated its egg-laying territory under a flat rock – one of the two ideal spots.


The olms mark their territory with chemical signals.
