Olm: Blind Cave Amphibian

The Olm, a close relative of the Axolotl, is a blind amphibian dwelling in underwater caves in Europe. It retains youthful traits throughout life, like external gills and a lack of color. Observations reveal some Olms not moving for nearly 7 years. They are only motivated to move when they mate, usually every 12.5 years. They can survive for up to 10 years without eating.
