描述：

Cafeteria (cafeteria) minuta (Ruinen, 1938) Larsen and Patterson, 1990. Cells are about 4 - 6 microns long with a small ventral groove. Two flagella emerge from the anterior end of the groove. The long anterior flagellum is about 2.5 - 4 times the cell length and beats with a sine-wave, and the posterior flagellum is about 1 - 1.5 times the cell length. When the cells swim, the anterior flagellum is directed forward and the posterior one trails. The cells may attach to the substrate by the tip of the posterior flagellum. Not common.
