Vannellida
The Vannellidae are a family of Amoebozoa, which are found in soil, fresh- and salt water. The most common genus is ''Vannella''. Description ''Vannellidae'' tend to be flattened and fan-shaped during motion, although some are long and narrow, and have a prominent clear margin at the anterior. In most amoebae, the endoplasm glides forward through the center of the cell, but vannellids undergo a sort of rolling motion with the outer membrane sliding around like a tank tread. These amoebae are usually 10-40 μm in size, but some are smaller or larger. ''Vannellidae'' are surrounded by an outer covering called the glycocalyx, which is generally 10-20 nm across, though the thickness varies among species. In some species, a layer of hair-like filaments called glycostyles protrudes from the glycocalyx. Taxonomy Molecular phylogenies include them in the class Flabellinia as a sister group In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises t ...

Amoebozoa Families
Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. In traditional and currently no longer supported classification schemes, Amoebozoa is ranked as a phylum within either the kingdom Protista or the kingdom Protozoa. In the classification favored by the International Society of Protistologists, it is retained as an unranked " supergroup" within Eukaryota. Molecular genetic analysis supports Amoebozoa as a monophyletic clade. Modern studies of eukaryotic phylogenetic trees identify it as the sister group to Opisthokonta, another major clade which contains both fungi and animals as well as several other clades comprising some 300 species of unicellular eukaryotes. Amoebozoa and Opisthokonta are sometimes grouped together in a high-level taxon, variously named Unikonta, Amorphea or Opimoda. Amoebozoa includes many of the best-known amoeboid ...

Flabellinia
The Flabellinia are a subclass of Amoebozoa. During locomotion the cells are flattened and have a clear layer called ''hyaloplasm'' along the front margin. Some form slender subpseudopodia projecting outward from the hyaloplasm, but the cell mass does not flow into these as in true pseudopodia, and advances without a definite central axis as in the Tubulinea. They also lack distinctive features like shells and flagella A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates. A microorganism may have f ..., and are united mainly by evidence from molecular trees. The group was originally created by Alexey Smirnov and his coauthors as the class Flabellinea, which was similar in composition to the group Discosea, proposed by Cavalier-Smith ''et al.'' (2004). In 2011, Smirnov accepted Discosea as a class and reduced Fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
