Octactis is a genus of silicoflagellates,[2] marine photosynthetic unicellular protists that take the form of either flagellates or axopodial amoebae.[4] Described by Josef Schiller in 1925, Octactis contains various species of marine phytoplankton, some of them responsible for algal blooms that are toxic to fish.[5]
