1. Three rare aquatic creatures known as baby dragons were displayed in an aquarium at Slovenia’s Postojna Cave. 2. The cave-dwelling animals, officially called proteus or olms, have pale pink skin, no eyesight, a long thin body, and four legs. 3. They live only in the waters of dark caves of the southern European Karst region. 4. The babies are up to 14 centimeters (5 inches) long and will reach 30 centimeters (12 inches) when fully grown. Olms can survive up to 8 years without food and have a lifespan of up to 100 years. 5. A special laboratory has been set up in the cave where the baby dragons are being monitored before they are all presented to the public.
