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 ...
Cave dwelling animals show different levels of adaptations to underground environment. According to a recent classification, animals living in terrestrial subterranean habitats can be classified into 3 categories, based on their ecology: troglobionts (or troglobites): species strongly bound to subterranean habitats;
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).

Some troglofauna live permanently underground and cannot survive outside the cave environment. Troglofauna adaptations and characteristics include a heightened sense of hearing, touch and smell. [1] Loss of under-used senses is apparent in the lack of pigmentation as well as eyesight in most troglofauna.
The deep biosphere is an ecosystem of organisms and their living space in the deep subsurface. [3] For the seafloor, an operational definition of deep subsurface is the region that is not bioturbated by animals; this is generally about a meter or more below the surface. [4] On continents, it is below a few meters, not including soils. [5]

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]
Many animals can glow in the dark. In a new study, scientists report that deep-sea corals that lived 540 million years ago may have been the first animals to glow, far earlier than previously thought.
