Chaos is a genus of bare, amoeboid unicellular organisms from the Euamoebida group . It is one of the longest known genera of the amoeba, its representatives can be unusually large with a diameter of several millimeters.
features
The species of the genus can actively move, they are either polypodial (thus form many cell processes ( pseudopodia ) for movement) or monopodial (form only one pseudopodia). The cells are usually larger than 0.5 millimeters in diameter, usually 1 to 2 millimeters, but can occasionally reach up to 5 millimeters.
All types are multinucleated with up to a thousand or more nuclei per cell. The cell nuclei are convex or elliptical disks on both sides and have a diameter of around 27 micrometers . Endosymbiotic zoochlorellae are absent.
The pseudopodia are cylindrical, often provided with ridged ridges, the uroid is mulberry-shaped . The cytoplasm often contains bipyramidal crystals.
Distribution, systematics
The types of chaos inhabit swampy fresh water. The type species is Chaos chaos , which was first described by Carl von Linné in 1758 . A selection:
