A 1mm-long Spirostomum with symbiotic chlorellae has been found in the oxygen-depleted sediment of a shallow fen pond in the South of England (UK). The ciliate lives amongst sediment debris, where it builds a lorica that covers about half the length of the ciliate. It is common to find several of the green Spirostomum cells sharing the same patch of sediment particles.
在英国南部一个浅水沼泽池塘缺氧的沉积物中发现了一种长1毫米、带有共生小球藻的旋口虫。这种纤毛虫生活在沉积物碎片中，它会构建一个覆盖自身长度约一半的外壳。经常会发现几个绿色的旋口虫细胞共享同一小块沉积物颗粒。
