Hentes writes: Giant unicellular organisms were found deep in the Mariana Trench. The cells, about 10cm in size, were found at depths up to 10,641 meters. The organisms, called xenophyophores, only exist in deep sea and thus are very hard to study. The researchers of the Scripps Institution of Oceanography used untethered autonomous probes called 'dropcams' to capture images of the organisms. Link to Original Source
