Miracle in Postojna Cave Aquarium - Proteus anguinus laying eggs

World history is once again being made in Postojna Cave – another important milestone has namely been marked recently.

For the first time in history we have witnessed an exceptional thing happening: eggs of the proteus, the most complex and... mysterious being of the underground world, being laid at a show cave. One of the proteus females started laying eggs in the aquarium of Postojna Cave, on 10 August, during the peak of the tourist season. This is a true miracle of nature and for us also proof that the cave and the life inside of it are being taken care in the best possible way. The new organisms coming to life in the cave attest to the fact that the conditions inside the aquarium are truly similar to those in nature. (foto Ciril Mlinar CIC for Postojnska jama, d.d.)
