This gigantic craggy abyss in the Pacific Ocean extends downwards for about 9 miles, and is roughly 150 miles long. Last Updated on November 12, 2019. Called xenophyophores, these single-celled organisms have likely become so big precisely because of their environment—the cold temperature, high pressure, and lack of sunlight all contribute to this amoeba’s relatively nightmarish size. As a consequence, little is known about their reproduction and other behaviors. A xenophyophore photographed in the Galapagos Rift by the US National Oceanic and Atmospheric Administration's Ocean Explorer. [8] Data has also suggested that microbial life forms thrive within the trench. Images of the xenophyophores were collected over the summer by researchers at Scripps who traveled to the Pacific Ocean's Mariana Trench, the deepest region on the planet. 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 previous depth record for xenophyophores was approximately 4.7 miles (7.6 kilometers). 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. They are fascinating giants that are highly adapted to extreme conditions but at the same time are very fragile and poorly studied. How deep is the Mariana Trench? with Scripps Institution of Oceanography at UC San Diego and National Geographic engineers carried out deep sea explorations at the Pacific Ocean chasm, discovered and documented the existence of xenophyophores in Mariana Trench (Giant amoebas, 2012). The Mariana Trench is more than 7 miles (11 kilometers) deep. Xenophyophores are giant unicellular organisms found throughout the world's oceans, at depths of up to 10,641 meters (6.6 miles). Giant single-celled animals have recently been discovered living in the deepest place on Earth – the Mariana Trench in the western Pacific Ocean. Using a “dropcam” (a digital video camera encased in a glass bubble designed to resist the massive water pressures encountered on the ocean floor), researchers from the Scripps Institution for Oceanography at the University of California, San Diego found populations of mysterious “xenophyophores” thriving at greater depths than ever before reported for this group. To put that in context, the average ocean depth is 12,000 feet, only a third of the Trench. The Mariana Trench is located in the NorthEast part of the Pacific Ocean., Where is the closest place to the Mariana Trench?, What is the closest country the Mariana Trench is by?
