	Pelobiont
		The most notable member is Pelomyxa pelustris, called the giant amoeba because of its size: usually 500-800 μm, but occasionally passing 3 mm in length.
		Pelomyxa are found in the mud at the bottom of freshwater streams.
		Pelomyxa are not picky eaters, and are full of vacuoles containing whatever food they happened across along with sand and other debris.

		Amoeba (Entamoeba) histolytica, Schaudinn, is the cause of tropical dysentery and hepatic abscess in man. Pelomyxa (fig.
		Absent or sluggish in marine forms, it is of constant occurrence in all fresh-water Rhizopods except Pelomyxa.
		A formation of numerous pseudopodiospores within Pelomyxa has been repeatedly described, and these have been seen to conjugate equally, the zygote becoming multinuclear.

	Archamoebae - Wikipedia, the free encyclopedia
		The other genera of archamoebae live in freshwater habitats, and are unusual among amoebae in possessing flagella.
		Early molecular trees based on rRNA placed the parasitic or commensal genera (entamoebids) and the flagellate genera (pelobionts) as separate groups that diverged from other eukaryotes very early on, suggesting that the absence of mitochondria was a primitive condition.
		The absence of dictyosomes in Pelomyxa was also considered primitive, which would separate it from Entamoeba, which has dictyosomes.

	Pelobionts - Wikipedia
		The most notable member is Pelomyxa, called the giant amoeba because of its size: usually 500-800 μm, but occasionally passing 3 mm in length.
		The monoflagellate amoebae Mastigamoeba and Mastigella show various ultrastructural similarities to Pelomyxa, and so are probably related.
		Other than these it does not appear to have any especially close relatives, and probably diverged from the rest of the eukaryotes early on.

		Pelomyxa is a microaeophilic amoeba living amongst the detritus in ponds and other freshwater.
		Pelomyxa is always monopodal, the only projections appear at the rear as colosomes.

		Pelomyxa is an amitochondriate amoeba with an internal flagella that may emerge.
		Pelomyxa (Figure H) can be flagellate and can undergo a lifecycle in which it changes form.

		Pelomyxa is one of the few eukaryotic organisms lacking mitochondria, the ATP producing organelles that supply energy for cell use.
		Pelomyxa’s energy needs are met by symbiotic bacteria living in its cytoplasm.

	Introduction to the Basal Eukaryotes
		Only about four species exist, all in the genus Pelomyxa -- and three of these species may turn out to be synonymous with the first species described, Pelomyxa palustris.
		Pelomyxa can tolerate very low oxygen levels; these protists lack mitochondria completely, but contain several types of symbiotic bacteria that fulfil the same function.
		Pelomyxa thus shows what eukaryotes were like at a very early stage in their evolution, before the appearance of true mitochondria.

		It is believed that this lack of mitochondria is a secondary absence.

		Pelomyxa palustris, be of such interest to cell biologists and evolutionary biologists?
		Pelomyxa palustris, however, the mitochondria is missing, and in its place are two kinds of bacteria that carry out the same role of producing the energy for the cell’s survival.
		Pelomyxa palustris eventually wrapped itself around an aerobic bacterium, and in the cell membrane, this bacterium evolved into what is today, the mitochondria.

		Eukaryotic mitochondria are probably derived from symbiotic nonsulfur purple bacteria, apparently in a single event because all mitochondria are the same.
		All eukaryotes but Pelomyxa and a few other groups possess mitochondria.
		The three classes are the chloroplasts of red algae, containing chlorophyll a, carotenoids, and phycobilins; the chloroplasts of brown algae, diatoms, and dinoflagellates, containing chlorophylls a and c, carotenoids, and other yellow-brown pigments; the chloroplasts of the green algae, euglenoids, and plants, containing chlorophylls a and b and carotenoids.

		They also lack two classic-eukaryotic organelles: mitochondria and Golgi.
		One example archezoan we observed in laboratory, Pelomyxa showed endosymbiotic bacteria and a particular form of locomotion called amoeboid movement.
		Another example archezoan enters the water supply from mammal excrement and is difficult to filter out from the water; this organism is known as Giardia.

		Excess water enters the cell by osmosis, as well as during the feeding process; this water accumulates in a spherical, clear contractile vacuole which contracts intermittently to release the water to the surroundings.
