In the caves of Slovenia, he encounters the peculiar creature known as the olm, a cave-dwelling blind salamander once believed to be a baby dragon.
The olm is a snake-like creature 25-30 cm long and weighing only up to 20 grams.
The blind salamander (Proteus anguinus), also known as the olm, has the longest lifespan of any amphibian, often living to over 70 in zoos, and with a predicted maximum age of over 100.
The olm is a Europe’s only cave adapted vertebrate, and has numerous adaptations for an underground life.
In the world of real life is freaky, check out the olm, which even has a name suited for a fantasy.
If this is correct it may be that the different White olm populations represent different species which resemble one another by convergent evolution, and which have partly or mostly fused as they have met up within the Dinaric karst system.
When salamanders invaded the Dinaric Karst: convergence, history, and reinvention of the troglobitic olm
Having said that, one of the most interesting contentions made recently about olms (Sket 1997) is that the different cave-dwelling olm populations may have evolved independently from different ancestral populations.
What might be the most fascinating fact concerning olms is the most poorly-known and least mentioned one: the 1986 discovery of a surface-dwelling olm, described in 1994 by Boris Sket and Jan Willem Arntzen.
Whatever, troglobitic olm populations must have evolved within the last 10,000 years or so, and presumably the specialised troglobitic morphology of living olms evolved during this time.
