Stories: THE OLM: Olm in Postojna Cave

Tourists watch a rare sight of the mother olm with her eggs in a live video feed from the big aquarium in Postojna Cave, Slovenia, March 15, 2016. In order not to disturb the olm or Proteus anguinus protecting its eggs, biologists covered the aquarium with black covers until the eggs hatch. This blind cave salamander was seen to lay eggs in its natural habitat of a cave only once before, in the same cave in 2013, but all were lost because of a stressful event.
