Remember, the number of animals in a cave is far fewer than their relatives on the surface. Types of Cave Life Cave animals fit into three categories based on the amount of time they actually spend in the cave. They are temporary cave residents which freely move in and out of the cave. These cave visitors seek out such a habitat from choice, and never complete their entire life cycle in the cave. Bats are usually the first trogloxenes that come to mind.
Some species prefer the constant temporature of caves for hibernation and to bear their young.
Bats, bears, skunks, moths, and people are examples of trogloxenes. Many of these animals are not dependent on the cave for their survival, they show no special adaptations to the cave environment. These cave loving animals can live in the dark zones of a cave, or they can also survive outside the cave. At times they will venture out in search of food. They are the true cave dwellers which spend their entire lives in the cave.
