There Be 'Baby Dragons'...Ready to Hatch in Slovenian Cave

Biologists at Postojna Cave, a 15-mile-long (24 kilometers) cave system in southwestern Slovenia, are waiting with bated breath for the arrival of up to 55 baby olms (Proteus anguinus). Olms are the largest of all cave-adapted animals, but they have long been enigmatic, Sessions and his colleague, Lilijana Bizjak Mali, of the University of Slovenia, wrote in an email to Live Science. Postojna Cave is a major tourist attraction, complete with an aquarium where visitors can see olms in captivity.
