Stephanoeca kentii is a loricate choanoflagellate, a marine unicellular organism that constructs a delicate basket-like structure (lorica) of siliceous strips surrounding its cell. It inhabits coastal and oceanic waters where it feeds on picoplankton bacteria. Choanoflagellates like this species are of scientific interest as the closest living unicellular relatives of animals.
