IMAGE GALLERY: HELIOZOA
Heliozoa exhibit a sphaerical cell-body containing one or more nuclei. Along the axopods, mitochondria, vesicles and other particles may be transported underneath the plasma membrane in a process called "granular streaming". Often, an apparently looser ectoplasm with pulsatile vacuoles can be distinguished from a denser endoplasm with nuclei. Mostly asexual propagation, sexual propagation known only from Actinophrysand Actinosphaerium.
