Figure 2. It is a famous place much-known for its varied sea lives and depth as well as the wonder of the nature below the surface of the earth. During a July 2011 voyage to the Mariana Trench, Scripps Institution of Oceanography researchers and National Geographic engineers documented the deepest known existence of xenophyophores, single-celled animals exclusively found in deep-sea environments. Alex Lee, By [Infographic: Tallest Mountain to Deepest Ocean Trench] Scientists say xenophyophores are the largest individual cells in existence. ", Lisa Levin, a deep-sea biologist also from Scripps, added: "As one of very few taxa found exclusively in the deep sea, the xenophyophores are emblematic of what the deep sea offers. Later they were classified as testate amoeboids (Arcellinida), then in their own phylum of Protista.

At the AGU meeting, astrobiologist Kevin Hand described what he called “an astonishingly bizarre microbial ecosystem” on talus blocks in the Sirena Deep (where the drop-cam video of the xenophyophores was taken). … The Mariana Trench was discovered by the Survey ship called HMS Challenger. Mariana Trench is part of WikiProject Geology, an attempt at creating a standardized, informative, ...

Xenophyophores have previously been observed in the New Hebrides Trench, in the south-west Pacific, at a depth of about 7500 km. Scientists say xenophyophores are the largest individual cells in existence. The ocean floor at such depth consists of a biogenous ooze composed of microscopic plankton shells from both animal and plant plankton. In contrast, other foraminiferans are commonly less than 1 mm across. The researchers spotted the life forms at depths up to 10,641 meters (6.6 miles) within the Sirena Deep of the Mariana Trench.

Originally thought to be sponges, they were later identified as single, gigantic cells, and classified as members of the kingdom Protista along with other single-celled organisms and simple multicellular life lacking specialized tissues. This may change in the future, however. Their expedition between 1872-1876 made the first attempt to measure the depth of the area. They are fascinating giants that are highly adapted to extreme conditions but at the same time are very fragile and poorly studied. Using a “dropcam” (a digital video camera encased in a glass bubble designed to resist the massive water … Giant Amoebas Discovered in Deepest Ocean Trench. The previous depth record for xenophyophores was approximately 7,500 meters (4.7 miles) in the New Hebrides Trench, although sightings in the deepest portion of the Mariana Trench have been reported.

Each was equipped with digital video recorders and lights (because it's dark down there), protected by a thick sphere of glass. To put that in context, the average ocean depth is 12,000 feet, only a third of the Trench. Xenophyophore in the Galapagos Rift.
