Plutomurus ortobalaganensis is the deepest terrestrial animal ever found on Earth, living at 1,980 metres (6,500 ft) below a cave entrance. [1] [2] It is a species of springtail endemic to the Krubera-Voronja cave system in Abkhazia, Georgia. It was discovered in the CAVEX Team expedition of 2010. [3]
This list of deepest mines includes operational and non-operational mines that are at least 2,224 m (7,297 ft), which is the depth of Krubera Cave, the deepest known natural cave in the world. The depth measurements in this list represent the difference in elevation from the entrance of the mine to the deepest excavated point.

A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).

Stratigraphic barriers, such as rock walls and layers, and fluvial barriers, such as rivers and streams, prevent or hinder the dispersal of these animals. [14] Consequently, subterranean fauna habitat and food availability can be very disjunct and precludes the great range of observed diversity across landscapes.
Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large sample ...
A deep-diving robot that chiseled into the rocky Pacific seabed at a spot where two of the immense plates comprising Earth's outer shell meet has unearthed a previously unknown realm of animal ...
The following is a list of rock types recognized by geologists. There is no agreed number of specific types of rock. There is no agreed number of specific types of rock. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type.
