This 'leptomyxid' amoeba was collected from a mineral deposit in a hot region of Nymph Creek. Leptomyxid amoebae are not common. Sometimes they fuse together into arrays measuring many millimeters in size (extremely large for protozoa). They eat bacteria, protists and detritus. The larger forms have multiple nuclei and often break apart to form many separate organisms.

Rhizamoeba (rye-sa-me-ba), a free-living naked amoeba which may adopt a variety of body forms from limax (slug-like) to more or less discoidal, to an extended fan-shape as here. Margins of the cell give rise to irregular thin pseudopodia. Nuclei round with central nucleolus. Phase contrast.

Margins of the cell give rise to irregular thin pseudopodia. Nuclei round with central nucleolus. The tuft of fine filaments is the uroid. Phase contrast.

An important feature of determination are filamentous appendages on the uroid (see inset). Scale bar indicates 50 µm. Sample from the pond Hegne Moor situated in the vicinity of Lake Constance.

Leptomyxa (lep-toe-mix-a) is an amoeba which can be quite large. Typically with an extended body form with thick strands of cytoplasm forming a network. Individual pseudopodia tend to be fine and tapering. Typically with multiple nuclei. From soils. Phase contrast.

Individual pseudopodia tend to be fine and tapering. This high magnification image shows the nature and texture of the cytoplasm, with a granular consistency reminiscent of vampyrellid amoebae) and many nuclei. From soils.
