Reticulosida
Reticulosida is an order of Endomyxa that was created by Cavalier-Smith in 2003, but subsequently emended in by Bass et al. in 2009 to include only one monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unisp ... family, the Filoretidae.

Aconchulinida
The vampyrellids (Order (biology), order Vampyrellida, class Vampyrellidea), colloquially known as vampire amoebae, are a group of free-living predatory amoebae classified as part of the lineage Endomyxa. They are distinguished from other groups of amoebae by their irregular cell shape with propensity to fuse and split like plasmodial organisms, and their biological life cycle, life cycle with a digestive cyst stage that digestion, digests the gathered food. They appear cosmopolitan distribution, worldwide in marine life, marine, brackish, freshwater and soil habitats. They are important predators of an enormous variety of microscopic organisms, from algae to fungi and animals. They are also known as aconchulinid amoebae (order Aconchulinida). Cell morphology and movement Vampyrellids are traditionally considered wikt:filose, filose amoebae, i.e. they generate slender pseudopodia (filopodia). They are naked, devoid of external structures such as scales, cell coats or a glycocalyx, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vampyrellidae
The family Vampyrellidae is a subgroup of the order Vampyrellida (or Aconchulinida) within the supergroup Rhizaria. Based on molecular sequence data, the family currently comprises the genus '' Vampyrella'', and maybe several other vampyrellid amoebae (e.g. ''Gobiella''). The cells are naked and characterised by radiating, filose pseudopodia (also referred to as filopodia) and an orange colouration of the main cell body. In former times the family Vampyrellidae contained several genera (e.g. '' Vampyrella'', ''Gobiella'', ''Leptophrys'', ''Platyreta'', ''Theratromyxa'') and was identical with the order Vampyrellida, also known under the name "Aconchulinida". However, based on molecular sequence data the family Vampyrellidae was restricted to a subgroup containing only the genus '' Vampyrella'', and a different family Leptophryidae was established for the genera '' Leptophrys'', '' Platyreta'' and '' Theratromyxa''. Characteristics When free-floating, the cell is spherical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endomyxa
Endomyxa is a group of eukaryotic organisms in the supergroup Rhizaria. They were initially a subphylum of Cercozoa and later a subphylum of Retaria, but several analyses have proven they are a phylogenetically separate lineage, and Endomyxa is currently regarded as its own phylum In biology, a phylum (; : phyla) is a level of classification, or taxonomic rank, that is below Kingdom (biology), kingdom and above Class (biology), class.

Ray Lankester
Sir Edwin Ray Lankester (15 May 1847 – 13 August 1929) was a British zoologist.New International Encyclopaedia. An invertebrate zoologist and evolutionary biologist, he held chairs at University College London and Oxford University. He was the third Director of the Natural History Museum, London, and was awarded the Copley Medal of the Royal Society. Life Ray Lankester was born on 15 May 1847 on Burlington Street in London, the son of Edwin Lankester, a coroner and doctor-naturalist who helped eradicate cholera in London, and his wife, the botanist and author Phebe Lankester. Ray Lankester was probably named after the naturalist John Ray: his father had just edited the memorials of John Ray for the Ray Society. In 1855 Ray went to boarding school at Leatherhead, and in 1858 to St Paul's School. His university education was at Downing College, Cambridge, and Christ Church, Oxford; he transferred from Downing, after five terms, at his parents' behest because Christ Church ...

Class (biology)
In biological classification, class () is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are domain, kingdom, phylum, order, family, genus, and species, with class ranking between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name – and not just called a ''top-level genus'' ''(genus summum)'' – was first introduced by French botanist Joseph Pitton de Tournefort in the classification of plants that appeared in his '' Eléments de botanique'' of 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construction, whic ...

Paraphyly
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protist (journal)
''Protist'' is a peer-reviewed scientific journal focusing on protists. It was founded as ''Archiv für Protistenkunde'' by editor Fritz Schaudinn in 1902, and originally published by Gustav Fischer and later Jena. The journal is now published by Elsevier, and is currently edited by Michael Melkonian (Botanical Institute, University of Cologne). The journal changed its name to ''Protist'' in 1998. Abstracting and indexing The journal is abstracted and indexed in the following bibliographic databases: According to the ''Journal Citation Reports'', the journal has a 2017 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a type of journal ranking.
