What depth fish can live?

The maximum depth at which fish have been found is about 8,370 meters (27,460 feet) in the Puerto Rico Trench. They belong to the snailfish family, which are some of the deepest-living fish in the ocean. These fish have adapted to the extreme conditions of the deep sea, including high pressure, cold temperatures, and lack of light. They have evolved special features, such as increased bone density and reduced metabolism, to withstand the harsh environment at these depths.
