Stories: THE OLM: Olm in Postojna Cave

Picture taken on March 15, 2016: A chamber in Postojna Cave, Slovenia, with the covered dwelling of an olm (Proteus anguinus) in the middle, where one of the rarest sights in biology was happening since January. The mysterious and very sensitive creature has laid 55 eggs and is now protecting them until they hatch. This has happened only once before, in 2013 in this same cave, but all the eggs were lost due to a stressful event.
