Which species is the first to be declared endangered as a result of deep sea mining?

Researchers of Queen's University Belfast found that the scaly-foot snail is the first species to be declared endangered as a result of deep-sea mining. The study also covers assessments of animals living in deep sea hydrothermal vents in the Indian Ocean. The International Union for Conservation of Nature (IUCN) has also added the scaly-foot snail to its global Red List, the international inventory of at-risk species. Also, 14 more species were found in a hydrothermal vent ecosystem that are to be included in the next edition of IUCN's Red List to be out in 2019.
