Dileptus Jonesi
''Dileptus'' is a genus of unicellular ciliates in the class Litostomatea. Species of ''Dileptus'' occur in fresh and salt water, as well as mosses and soils. Most are aggressive predators equipped with long, mobile proboscides lined with toxic extrusomes, with which they stun smaller organisms before consuming them. 13 species and subspecies of ''Dileptus'' are currently recognized.Vďačný, Peter, and Wilhelm Foissner. Monograph of the dileptids (Protista, Ciliophora, Rhynchostomatia). Land Oberösterreich, Biologiezentrum/Oberösterreichische Landesmuseen, 2012 ''Dileptus'' species have served as model organisms, used in the study of ciliary patterns, ontogenesis, conjugation and food acquisition. Appearance and characteristics ''Dileptus'' bodies are typically narrow or cylindrical, and have a macronucleus made up of more than a hundred scattered nodules. During cell division, these nodules divide individually. At the front end of the cell is a mobile proboscis. The cyto ...

Unicellular
A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. All prokaryotes are unicellular and are classified into bacteria and archaea. Many eukaryotes are multicellular, but some are unicellular such as protozoa, unicellular algae, and unicellular fungi. Unicellular organisms are thought to be the oldest form of life, with early protocells possibly emerging 3.8–4.0 billion years ago. Although some prokaryotes live in colonies, they are not specialised cells with differing functions. These organisms live together, and each cell must carry out all life processes to survive. In contrast, even the simplest multicellular organisms have cells that depend on each other to survive. Most multicellular organisms have a unicellular life-cycle stage. Gametes, for example, are r ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Christian Gottfried Ehrenberg
Christian Gottfried Ehrenberg (19 April 1795 – 27 June 1876) was a German naturalist, zoologist, comparative anatomist, geologist, and microscopist. Ehrenberg was an evangelist and was considered to be of the most famous and productive scientists of his time. Early collections The son of a judge, Christian Gottfried Ehrenberg was born in Delitzsch, near Leipzig. He first studied theology at the University of Leipzig, then medicine and natural sciences in Berlin and became a friend of the famous explorer Alexander von Humboldt. In 1818, he completed his doctoral dissertation on fungi, ''Sylvae mycologicae Berolinenses.'' In 1820–1825, on a scientific expedition to the Middle East with his friend Wilhelm Hemprich, he collected thousands of specimens of plants and animals. He investigated parts of Egypt, the Libyan Desert, the Nile valley and the northern coasts of the Red Sea, where he made a special study of the corals. Subsequently, parts of Syria, Arabia and Abyss ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Dileptus Margaritifer
''Dileptus margaritifer'' is a species of ciliates in the family '' Dileptidae.'' It is common in freshwater streams, lakes and ponds, as well as mosses and soil. The species has been found on every continent except Antarctica.Vďačný, Peter, and Wilhelm Foissner. Monograph of the dileptids (Protista, Ciliophora, Rhynchostomatia). Land Oberösterreich, Biologiezentrum/Oberösterreichische Landesmuseen, 2012: 294-314 Because of a taxonomic error by one researcher in the 19th century, specimens of ''Dileptus margaritifer'' have been misidentified in most studies as ''Dileptus anser'' (Müller, 1773). Morphology ''Dileptus margaritifer'' has a slender body, usually about 450 µm in length and very flexible, narrowing at the posterior into a small, sharp tail. At its front, it has a broad and tapering proboscis, reminiscent of an elephant's trunk in its shape and flexibility, but with a flattened rather than round cross-section. The proboscis is 1/3 to 1/2 of the total body len ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
