Troglobites are animals that have adapted to live in the dark depths of caves. One animal that fits this definition is the Olm, an aquatic salamander that has translucent skin that resembles that of a human. Though they are born with eyes, these eyes regress until they become fully blind by adulthood. These animals use chemical and electrical receptors, along with smell and hearing, to find prey. One of the most fascinating facts about these creatures is that they can go around 10 years without food and live to be about 100 years old.
