Scientists describe the deepest terrestrial arthropod ever found

       Scientists have recently described the deepest terrestrial animal ever found, together with 4 new species for science. These animals are springtails. These animals were collected from the University of Aveiro. The World's deepest cave, Krubera-Voronja, reaching the depth of -2.191 meters below ground level, is located in Abkhazia, an area near the Black Sea in the mountains of Western Caucasus, being the only cave in the World, more than 2 kilometres deep. 
       The discovery of life in such deep systems begins new discoveries about the way we look at life on Earth. with no light and limited food, unique cave animals have adapted to the conditions. They lack body pigmentation, they have no eyes and have been developing morpho-physological strategies for survival at such depth. One of the species has, for example, chemoreceptor, a highly specialised type of the habitual post-antennal organ of the springtails.
