Eyeless animals can seem almost alien compared to those we're used to, but a lack of sight doesn't have to mean a loss in senses or abilities.
The one in the picture above is an olm, which lives in the southeastern Europe’s Dinaric Alps. The people of Slovenia and Croatia call it the "human fish" because of its pale, pinkish flesh. The olm can live up to 100 years, but it stays in its gill-breathing larval stage its entire life. The critter is such an icon in Slovenia that it was even featured on their coins before the country switched to the Euro.
