Many forms of heliostats have been devised, the earliest having I been described by Wilhelm Jacob s’Gravesande in the 3rd edition of his Physices elemen~a (1742).

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 Actinophrys and Actinosphaerium.

The heliozoa are radially symmetrical unicells characterised by the possession of long, slender cytoplasmic arms called axopodia, stiffened by a complex structure of microtubules. Cytoplasm flows continuously back and forth along the axopodia, conveying bacteria and anything else which adheres to them back to the cell body. Larger prey such as algal cells may become enmeshed in the axopodia and similarly incorporated into the cell body.

Sonnentierchen, Heliozoa - German
URL: http://home.t-online.de/home/ghstanjek/pl15.htm

Zur Ordnung der Heliozoa oder Sonnentierchen zählt das ca. 250 µm große Strahlenblättchen. Die zahlreichen Strahlen werden Axopodien genannt. Sie sind feine, offensichtlich giftige Plasmafortsätze, die durch eine gelartig verfestigte Plasmaachse verstärkt werden. Vorbeischwimmende Wimper- oder Rädertiere werden gelähmt oder vergiftet und anschließend von den Pseudopodien, das sind bewegliche, kontrahierfähige Scheinfüßchen, ins Innere gezogen und verdaut.
