The unusual birth of "dragon" offspring in Postojna Cave
People used to believe that the human fish was the offspring of dragons. And still today we believe that there is something extraordinary, even mythical, in them. The human fish is one of the most impressive dwellers of the karst underground. Postojna Cave can also boast a unique attraction. On 30 May 2016, the first offspring hatched from one of the eggs of the human fish. This was a remarkable historical event that captured the attention of the entire global public. Today, Postojna Cave takes pride in its 21 baby dragons. Three of them have already left their "nest" – a cave laboratory where they were given all possible care. "World stars" since birth, they are waiting to meet you!
What makes the baby dragons such stars?
You may be wondering why human fish are so special. Although they have lived in caves for millions of years, humans first observed them only 400 years ago. Believing that there was a fearsome dragon living inside Postojna Cave, people thought these animals were in fact baby dragons!
Today, we know that the human fish, also known as the proteus, is the only vertebrate living exclusively underground. This small animal is extremely well adapted to life in the darkness. Its skin lacks any protective pigmentation, so it is pale pink in colour and resembles the skin of people, which is why it was given the name “human fish”.
The human fish only reproduces every six or seven years. Of over 100 eggs deposited by a female olm in its lifetime in its natural environment, only two offspring would reach maturity. This is why the survival of 21 baby dragons out of 64 hatched eggs in the Postojna Cave laboratory is a truly amazing achievement.
