Actinosphaerium is a genus of heliozoa, amoeboid unicellular organisms with many axopodial filaments that radiate out of their cell. It is classified within the monotypic family Actinosphaeriidae and suborder Actinosphaerina. Species of Actinophrys are distinguished by their large number of nuclei in each cell. Their axopodia sometimes terminate on the surface of nuclei. Vacuoles are abundant in the periphery of the cytoplasm.
