Arcella

Arcella is a genus of testate amoebae in the order Arcellinida, commonly found in ponds, wetlands, moss, and soil. It is distinguished by a radially symmetrical organic shell, which features a central aperture through which pseudopods are extended. Recognized for its broad ecological adaptability, Arcella has been described as "probably the most ecologically successful Arcellinid taxon", with several species exhibiting a cosmopolitan distribution across diverse environments. thumb|Dorsal view of Arcella conica

==History and classification== thumb|left|Illustrations of Arcella vulgaris by C. G. Ehrenberg, 1830.|320x320px The genus Arcella was established in 1830 by the German zoologist C. G. Ehrenberg, who designated Arcella vulgaris as the type species. Over time, numerous species were added to the genus, and by the early 21st century, approximately 51 nominal species, 71 varieties, and 27 distinct forms had been recognized.
