Spelaion

Spelaion is a term that has seen some usage in the context of exploring and studying caves. It is derived from the Greek word "spelaion," which translates to "cave." While not a universally standardized scientific term, it is sometimes employed by speleologists or those involved in cave exploration to refer to the study of caves, the exploration of subterranean spaces, or the natural environment found within caves.

The concept of spelaion encompasses a wide range of activities and disciplines. This can include the geological formation and evolution of caves, their unique ecosystems and the specialized life forms that inhabit them, and the archaeological or paleontological significance of cave sites. The term may also be used to describe the process of mapping and surveying cave systems, as well as the challenges and techniques associated with descending into and navigating these underground environments.

In some contexts, spelaion might be used informally to distinguish the scientific or exploratory aspect of cave study from more recreational forms of caving or spelunking, though this distinction is not always strictly maintained. The study of caves itself is a multidisciplinary field, drawing on geology, biology, archaeology, and hydrology, among others.
