In one of the caves of Slovenia, three "baby dragons" - Proteus, which hatched here in 2016, were on display. Access to rare amphibians is open to only 30 visitors per day.
Proteas are ancient amphibian predators that live up to a hundred years and produce offspring once a decade. In Postojna Cave in Slovenia, biologists managed to breed 21 Proteus cubs, three of which they decided to demonstrate to the public. In order to preserve a rare and vulnerable species, access to the rest of the population is closed.
Proteus live in underground rivers, and therefore are completely blind. They reach a length of 35 cm and have four small limbs. They are characterized by three branched branchial processes on the sides of the head. Proteus have thin pink skin that allows you to see the internal organs. Curiously, a leisurely metabolism allows these amphibians to go without food for up to ten years.
Proteas live mainly in the Balkan underground rivers, and in the Postojna cave, 50 km from the Slovenian capital Ljubljana, according to biologists, they have been living for millions of years.
