| | Cave - Wikipedia, the free encyclopedia |
 | | Sea caves are very common at all coasts of the world, but as they are restricted to the zone where waves work on the rocks of the coast they are generally rather small. |
 | | Cave inhabiting animals can be categorized as troglobites (cave limited-species), troglophiles (species which can live their entire lives in caves, but also occur in other environments), trogloxenes (species which utilize caves, but must leave the caves to complete their life cycle) and accidentals. |
 | | Because of the fragile nature of the cave ecosytem, and the fact that cave regions tend to be isolated from one another, caves harbor a number of endangered species, such as, for example the Tooth cave spider, Liphistiidae Liphistius trapdoor spider and the Gray bat. |
