Cave creatures can be divided into different groups based on how much time they actually spend inside the cave. For example, some animals hang out near the entrance and come and go while others spend their entire lives in the confines of the cave. The term trogloxene (translated as cave guests) refers to those creatures that freely come and go from the cave. These animals may choose a cave for temporary shelter or to raise their young. Examples include bears, raccoons, bats, and humans to name a few. Caves’ constant temperatures and protection from the elements make them a reasonable choice for many animals.
