(n.) Troglobites are organisms that are unable to live outside of the cave environment; they are also called obligate cavernicoles. An example from New Mexico caves is the troglobitic dipluran. Animals that have adapted to the cave environment show some combination of lost coloration (appear translucent white), low metabolic rate, reduced or no eyes, longer (attenuated) appendages, changes in circadian rhythms, smaller body size, and enhanced sensory mechanisms.
