Deep in a Slovenian cave , a blind fire hook – once thought to be adragon ’s issue – dwells in darkness . think to know formore than a century , these wight regurgitate just once or doubly every tenner , and this particular female person has been caught in the act of laying around 60 ball . AsBBC Newsreports , a few of these eggs appear to be showing augury of growing .
These aquatic amphibian critter are called Proteus anguinus , and they interpret the only single cave - dwelling craniate in Europe . For over 200 million years , their evolutionary derivation exist in a relatively static environment , so they are implausibly vulnerable to environmental variety – especially their eggs .

The visual aspect of a seemingly workable clutches of eggs within the labyrinthinePostojna cave systemis seen as a remarkable event by researcher . “ This is very coolheaded – it is quite extraordinary , " say Primoz Gnezda , a biologist working at Postojna , toldBBC News . “ But also , we are quite scared that something will go wrong , because the egg are very tender . ”
Harsh light can damage the orchis , as can slight changes in water temperature and tone . To this end , the research worker have hide the female person and her eggs in a shrouded storage tank with carefully command water . Although she can smell the approach of any peckish , egg - eating creature using specialised electro - sensitive snout organ , the investigator have removed all predators from the scene .

The olm is aparticularly enigmaticand elusive fauna , and nut or larvae are never found in the wilderness , perhaps because they ’re just too well - hidden within their erectile habitats . The fact that these fresh eggs were laid in one of the most tourist - heavy theatrical role of the cave is a stroke of fortune ; if they hatch , researcher will be able-bodied to observe the complete development of these “ baby dragons , ” live in their instinctive home ground , in real - sentence .
free-base on anothercaptive olm colonyin France , biologists think these eggs necessitate 120 days to hatch . This estimate is based on an ambient temperature of 11 ° C ( 51.8 ° F ) , but as the Slovenian caves are 9 ° degree centigrade ( 48.2 ° F ) , embryo growth will take middling longer .

The mother - to - be is , as aforementioned , blind , so she ’s heavily reliant on hersense of olfactory modality . Using it , she can smack the dispute between eggs that are thrive and those that have stopped developing . As solid food is so scarce in the cave , she eats the eggs that turn over out to be unfertilized – although she could live for 10 years without any food if motivation be .
For now , the eggs and the female are on their own , and the researchers are waiting with bated breath . A successful hatching will be seen as a huge boost for theendangered species , which is becoming increasingly threatened in the modernistic existence by pollution and home ground disturbance .
In 2013 , another of Postojna ’s Proteus anguinus laid testis , but none of them concoct . regrettably , many were gobbled up by other olm .
