Arcellinida

Test of Cyclopyxis eurystoma, copyright Ferry Siemensma.

Belongs within: Tubulinea.
Contains: Arcella, Trigonopyxidae, Hyalospheniidae, Centropyxiidae, Plagiopyxidae, Difflugia.

The Arcellinida, testate amoebae, are a group of amoebozoans which contain themselves inside an organic or mineral extracellular test of either self-secreted elements (calcareous, siliceous, or chitinoid) or recycled mineral particles bound together, with a single main opening. Pseudopodia are conical and pointed in species of Phryganellina, and digitate and granular in Difflugina and Arcellina (Adl et al. 2012).
