Xenophyophores are multinucleate unicellular organisms found on the ocean floor throughout the world's oceans, at depths of 500 to 10,600 metres (1,600 to 34,800 ft). [3][4] They are a kind of foraminiferan that extract minerals from their surroundings and use them to form an exoskeleton known as a test.

Oct 26, 2011 · Huge "ameobas" have been spotted in the Mariana Trench, the deepest part of the world's oceans. The giants of the deep are so-called xenophyophores, sponge-like animals that—like amoebas—are made...

Gromia sphaerica is a large spherical testate amoeba, a single-celled eukaryotic organism and the largest of its genus, Gromia. The genus itself contains about 13 known species, 3 of which were discovered as late as 2005. [1] It was discovered in 2000, along the Oman margin of the Arabian Sea, at depths around 1,163 to 1,194 meters (3,816 to ...

An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods. [2]

Nov 8, 2011 · A summer research expedition organized by scientists at Scripps Institution of Oceanography at UC San Diego has led to the identification of gigantic amoebas called xenophyophores at one of the deepest locations on Earth.

Oct 24, 2011 · Scientists at Scripps Institution of Oceanography at UC San Diego have identified gigantic amoebas at one of the deepest locations on Earth — the Pacific Ocean’s Mariana Trench.

Amoeba can be found in deep-sea hydrothermal vents, which are areas on the ocean floor where hot water and minerals are released from the Earth’s crust. Examples of amoeba found in hydrothermal vents include the marine amoeba ( Vampyrellidium spp ) and the parasitic amoeba ( Vahlkampfia spp ).

Oct 21, 2011 · Giant amoebas and the deepest living jellyfish yet found were discovered in a deep sea mission to the Mariana Trench, the deepest spot on Earth.

Oct 24, 2011 · Scientists have discovered a community of 4-inch amoebas living at the bottom of the Mariana Trench, the deepest known part of the world's oceans.

Oct 29, 2020 · Amoeba is an aquatic, single-cell (unicellular) organism with membrane-bound (eukaryotic) organelles that has no definite shape. It is capable of movement. When seen under a microscope, the cell looks like a tiny blob of colorless jelly with a dark speck inside it.

Squamamoeba japonica n. g. n. sp. was isolated and described from marine bottom sediments collected at a depth of ca. 2700 m in the Sea of Japan. Trophic amoebae of this species are elongated and flattened, with a wide anterior hyaloplasm producing numerous ventral subpseudopodia for adhesion to the …

In an effort to explore the genomic diversity and investigate extraordinary behavior observed among the Amoebozoa, we used integrated omics approaches to study this enigmatic marine amoeba. Omics data, including single-cell transcriptomics and cytological data, demonstrate that Trichosphaerium sp. possesses the complete meiosis toolkit genes.

Oct 24, 2011 · Deep in the Mariana Trench, about seven miles below the surface, researchers found huge single celled amoebas, making them not only completely surprisng and amazing, but also the creatures...

Oct 22, 2011 · The team documented the deepest known existence of xenophyophores, single-celled animals exclusively found in deep-sea environments.

Article title: Squamamoeba japonica n. g. n. sp. (Amoebozoa): a deep-sea amoeba from the Sea of Japan with a novel cell coat structure.

Amoeba is a genus of single-celled amoeboids in the family Amoebidae. [2] The type species of the genus is Amoeba proteus , a common freshwater organism, widely studied in classrooms and laboratories.

Apr 18, 2010 · Results from the latest Census of Marine Life study are in, highlighting spectacular examples of hard-to-see underwater microbes, part of a wider study involving four research groups looking at...

Jan 1, 2013 · Squamamoeba japonica n. g. n. sp. was isolated and described from marine bottom sediments collected at a depth of ca. 2700 m in the Sea of Japan. Trophic amoebae of this species are elongated and flattened, with a wide anterior hyaloplasm producing numerous ventral subpseudopodia for adhesion to the substratum.

Sep 7, 2012 · Two strains of lobose amoebae have been isolated from the deep-sea bottom sediments of the Sea of Japan (3.6km deep) and Western Atlantic Ocean (5.1km deep).

Shell of Cylindrifflugia acuminata: an agglutinated test made up of mineral particles glued together with secretions from within the cell. Testate amoebae (formerly thecamoebians, Testacea or Thecamoeba) are a polyphyletic group of unicellular amoeboid protists, which differ from naked amoebae in the presence of a test that partially encloses the cell, with an …
