Massisteriidae

	Massisteriidae Massisteriidae is a family of granofilosean protists within the phylum Cercozoa. Taxonomy Massisteriidae contains two genera: ''Massisteria ''Massisteria'' is a genus of Cercozoa.

	Minimassisteria ''Minimassisteria'' is a marine bacterivorous genus of protists with only one species, ''M. diva'', that presents three different lifestyle forms. It has a widespread geographic distribution. It is an amoeboflagellate most closely related to ''Massisteria'', and together comprise the family Massisteriidae. Morphology and behavior ''Minimassisteria'' are trimorphic (i.e. with three forms) filose amoeboflagellates with two flagella. Their life cycle has a trophic phase that feeds by non-anastomosing filose pseudopodia (i.e. filopodia) that bear evident granules along their length. There is a distinct swimming form and, unlike its closest relative ''Massisteria'', a crawling form with a thicker non-granular anterior filopodia used for traction. Feeding form. These cells, known as trophonts, have a flattened cell body attached to the substrate, measuring 2.3 to 5.0 μm in diameter. Between 1 and 15 delicately thin filopodia radiate from the cell body up to 52 μm in length, with up ... [...More Info...] [...Related Items...] OR:* [Wikipedia] [Google] [Baidu]
	Granofilosea Granofilosea is a class of cercozoans in the subphylum Filosa. Three groups that were traditionally considered heliozoans belong here: the Heliomonadida, Desmothoracida and Gymnosphaerida, which were recently grouped into the new class of Granofilosea.

picture info	Protists A protist () is any eukaryotic organism (that is, an organism whose cells contain a cell nucleus) that is not an animal, plant, or fungus. While it is likely that protists share a common ancestor (the last eukaryotic common ancestor), the exclusion of other eukaryotes means that protists do not form a natural group, or clade. Therefore, some protists may be more closely related to animals, plants, or fungi than they are to other protists. However, like the groups ''algae'', ''invertebrates'', and ''protozoans'', the biological category ''protist'' is used for convenience. Others classify any unicellular eukaryotic microorganism as a protist. The study of protists is termed protistology. History The classification of a third kingdom separate from animals and plants was first proposed by John Hogg in 1860 as the kingdom Protoctista; in 1866 Ernst Haeckel also proposed a third kingdom Protista as "the kingdom of primitive forms". Originally these also included prokaryotes, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Cercozoa Cercozoa is a phylum of diverse single-celled eukaryotes. They lack shared morphological characteristics at the microscopic level, and are instead defined by molecular phylogenies of rRNA and actin or polyubiquitin. They were the first major eukaryotic group to be recognized mainly through molecular phylogenies. They are the natural predators of many species of microbacteria and Archea. They are closely related to the phylum Retaria, comprising amoeboids that usually have complex shells, and together form a supergroup called Rhizaria. Characteristics The group includes most amoeboids and flagellates that feed by means of filose pseudopods. These may be restricted to part of the cell surface, but there is never a true cytostome or mouth as found in many other protozoa. They show a variety of forms and have proven difficult to define in terms of structural characteristics, although their unity is strongly supported by phylogenetic studies. Diversity Some cercozoans are grouped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Massisteria Marina ''Massisteria marina'' is a species of small marine phagotrophic protists that normally feed on bacteria. Individuals live associated with sediment particles and suspended detritus in litoral or marine waters. It is found at marine sites all around the world. Its predominantly sedentary lifestyle was a discovery that challenged the concept of bacterivorous protists as constantly active hunters, and its permanent association with detritus particles is uncommon among flagellates. Morphology ''M. marina'' are unicellular amoeboflagellates composed of a flattened irregular star-shaped cell body measuring 3–9 μm in diameter, pressed against the substrate, with several (2 to 10) thin branching filamentous pseudopodia, extrusomes close to the substrate, and two short inactive flagella that measure 4–6 μm. The arrangement of their pseudopodia are reminiscent of freshwater species ''Gymnophrys cometa'', which usually has only two pseudopodial trunks but more can arise. Behavior ''M. ...
