Descriptive of fauna (animals) and flora (plants) which live in tunnels on a permanent basis: The troglobiotic species of creatures sense their surroundings primarily by touch, often using smell to track down food; for example, cave crickets detect food by using their antennae, while spiders use their feet.

In subterranean streams and pools, troglobiotic fish and salamanders sense vibrations in the water.

A creature which lives entirely in the dark parts of underground enclosuress: Troglobites are cave-dwelling creatures that navigate without eyes, go for weeks or months without food, and are believed to be able to exist for more than a hundred years.

2.

troglocoline (adjective), more troglocoline, most troglocoline
A reference to living entities that exist in underground passages or hollows: All troglncoline communities that survive in deep caves depend on replenishment from the outside world, whether through underground streams, or food brought in by other animals.

Many troglocoline species include certain species of fish, crayfish, and flatworms; however, most of them have a ghost-like pallor or unnatural paleness on their outer surfaces and cannot see and some don't even have any eyes.

Some computer programmers are thought of as being troglodytes because they work alone with their machines and have little contact with other people.

The term troglodyte doesn't necessarily apply just to prehistoric cave dwellers. It also describes someone who lives in a dingy domicile or people who are so socially inept or culturally deprived that they seem to have just emerged from a subterranean cavity into the "blinding light of civilization" or those whose thinking or behavior is considered to be uncivilized and backward.
