The NPS also collaborates with partners to extend the benefits of natural and cultural resource conservation with local communities across the country, such as through the National Natural Landmarks Program. The National Park Service (NPS) has the awesome responsibility of managing unimpaired for this and future generations some of the most spectacular landscapes and their inhabitants (including caves and cave critters), as well as cultural sites that tell important stories. Therefore, there are many different agencies, organizations, and individuals that play a role in caring for these underground worlds and their inhabitants. Even though individual species population's may be limited, cave critters can be found all over the world, including in caves on both publicly and privately-owned lands. Thus, most cave species have small populations, restricted ranges, and low rates of reproduction. While surface and subsurface habitats are connected in many ways, individual caves are often highly fragmented and separate from one another. Some cave crayfish have been found to live up to 50 years! Other organisms shift to utilizing whatever resource is most prevalent in the cave for their food source, such as bacteria that consume hydrogen sulfide.Īdaptations to such specialized environments are possible because cave critters don’t roam far from home. With low-oxygen air in some caves and months without food, some critters have developed super-slow metabolisms and because they live slowly, they also live longer. Visual cues within a world of complete darkness have little value and thus many troglobites are colorless, blind and even eyeless. While people who love to go caving, love caves and have no physical adaptions to caves, they are trogloxenes and not troglophiles! Troglobite-Cave Adaptedįulltime cave dwellers, called troglobites (troglo = cave, and bios = life), have amazing adaptations that allow them to live permanently in completely dark, low-energy environments. They too have no special adaptations to the cave environment. They are called troglophiles (troglo = cave and phileo = love). Some critters can spend their entire life underground or on the surface.
They have no special adaptations to the cave environment and can even live their entire lives outside of caves. Almost all trogloxenes must go to the surface or to the cave entrance for food. Organisms, like bats, bears and other creatures, that may only live a part of their lives inside of caves are called trogloxenes (troglo = cave, xenos = guest).
