Olm is a rare salamander, which lives in an underwater cave in Bosnia and Herzegovina. Scientists observing one Olm have noted that it has not moved for 2,569 days (approximately 7 years). The amphibian salamanders, known as olms, are blind and can live up to 100 years. Olms are only motivated to move when they mate, usually every 12.5 years.
