Abstract

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.
