Euamoebida
The Tubulinea are a major grouping of Amoebozoa, including most of the more familiar amoebae genera like ''Amoeba'', '' Arcella'', '' Difflugia'' and '' Hartmannella''. Characteristics During locomotion most Tubulinea have a roughly cylindrical form or produce numerous cylindrical pseudopods. Each cylinder advances by a single central stream of cytoplasm, granular in appearance, and has no subpseudopodia. This distinguishes them from other amoeboid groups, although in some members this is not the normal type of locomotion. Classification This class was anticipated by some biologists such as Jahn, who grouped all amoebae with granular pseudopodia together, but most split the lobose amoebae into testate Testacealobosia and naked Gymnamoebia. These latter are polyphyletic, but molecular trees by Bolivar ''et al.'' identified a core monophyletic subgroup. Subsequent studies showed the testate lobose amoebae belong to the same group, which was thus renamed Lobosea ''sensu stric ...

Microcoryciidae
The Tubulinea are a major grouping of Amoebozoa, including most of the more familiar amoebae genera like ''Amoeba (genus), Amoeba'', ''Arcella'', ''Difflugia'' and ''Hartmannella''.

This distinguishes them from other amoeboid groups, although in some members this is not the normal type of locomotion.

Amoebozoa
Amoebozoa is a major Taxonomy (biology), taxonomic group containing about 2,400 described species of Amoeba, amoeboid protists, often possessing blunt, fingerlike, Pseudopod#Morphology, lobose pseudopods and tubular mitochondrial cristae. In traditional classification schemes, Amoebozoa is usually ranked as a phylum within either the kingdom (biology), kingdom Protista or the kingdom Protozoa. In the classification favored by the International Society of Protistologists, it is retained as an unranked "supergroup (biology), supergroup" within Eukaryota. Molecular genetics, 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, named Amorphea. Amoeboz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corycida
Corycidia (alternatively spelt Corycida) is a clade of amoeboid protists within the eukaryotic supergroup (biology), supergroup Amoebozoa. It contains all amoebae of the families Microcoryciidae, which was previously regarded as Arcellinida (an order of testate amoebae), and Trichosphaeriidae, which contains the sole genus ''Trichosphaerium''. Taxonomy Corycidia is defined as the least inclusive clade containing ''Amphizonella'', ''Diplochlamys (protist), Diplochlamys'' and ''Trichosphaerium''. It was discovered in 2017 through a phylogenomic study by Senghuo Kang and coauthors, published in the journal ''Molecular Biology and Evolution''. It is supported by independent analyses. As of 2019, it is accepted by the International Society of Protistologists as part of the modern cladistic classification of eukaryotes, although under the alternative spelling Corycida. The name Corycidia is derived , referring to the "leathery" test (biology), test that members of the clade have. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhizamoebidae
''Rhizamoeba'' is a small genus of free-living Marine life, marine naked Lobosa, lobose Amoebozoa, amoebae in the monotypic family Rhizamoebidae in the order Leptomyxida. It is most closely related to ''Leptomyxa'' and ''Flabellula'', and some species have been moved to ''Leptomyxa'' due to molecular data. Morphology Members of ''Rhizamoeba'' are characterized by their morphology when they move, which is usually monopodial (with a single ramification), alternating between a slug-like shape and a fan shape. They have either one nucleus (cell), nucleus or multiple (less than 50) nuclei. Classification The paraphyly of the genus caused the transfer of two previously rhizamoeban species into ''Leptomyxa'': ''Leptomyxa australiensis, R. australiensis'' and ''Leptomyxa neglecta, R. neglecta''. As a result, only 3 species are currently confirmed as ''Rhizamoeba'': * ''Rhizamoeba saxonica'' * ''Rhizamoeba polyura'' * ''Rhizamoeba matisi'' Other possible species are not yet confirmed ...
