蜷絲球蟲綱

蜷絲球蟲綱（學名：Filasterea）是動物總界蜷絲動物下的一個類群，包括小球虫（英语：Ministeria）與快孢子虫（英语：Capsaspora）兩類單細胞變形蟲。蜷絲球蟲在演化樹上為領鞭毛動物（包括領鞭毛蟲和動物界）的姐妹群，此分類單元於2008年基於分子種系發生學的證據提出。 快孢子虫（英语：Capsaspora）僅有單一物種Capsaspora owczarzaki，最早自淡水螺類紅扁蜷（英语：Biomphalaria glabrata）體內採得，一度被認為是一種核形蟲，後經分子證據顯示其與動物較為接近，應屬動物總界；小球虫（英语：Ministeria）則有Ministeria vibrans（英语：Ministeria vibrans）與Ministeria marisola兩種，為自海水樣本中採得。2017年又有另一屬生物Pigoraptor被發表描述，包括Pigoraptor vietnamica與Pigoraptor chileana兩種，皆自淡水湖樣本中採得，分子證據顯示其屬於蜷絲球蟲，且與快孢子虫關係較近。 以下為動物總界與真菌總界生物的演化樹： Shalchian-Tabrizi K, Minge MA, Espelund M, et al.
