Heliomonadida

The Heliomonadida (formerly Dimorphida) are a small group of heliozoan amoeboids that are unusual in possessing flagella throughout their life cycle.

==Classification== Genetic studies place them among the Cercozoa, a group including various other flagellates that form filose pseudopodia. This order has been placed into the new class of naked filose cercozoans called Granofilosea. There are two genera in this order: Heliomorpha, a tiny organism found in freshwater the larger Tetradimorpha, which is distinguished by having four rather than two flagella.
