Octactis is a genus of silicoflagellates, marine photosynthetic unicellular protists that take the form of either flagellates or axopodial amoebae. 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.W CalCOFI holds 180 observations of it in 1 dataset between 1996 and 2022, across 2 taxa under it.R
