Clathrulina elegans

This organism is traditionally regarded as a heliozoon, but its usual form is as an amoeba living inside a a perforated lorica 20 - 30 microns in diameter, and from which it extends thin stiff pseudopodia. The lorica is located at the end of a hollow stalk up to 200 microns long. The stalk and lorica are organic and become brown with age. The amoeba divides and produces flagellated dispersal stages. Occasionally common and also reported from the Northern Hemisphere.

Clathrulina elegans is a species of heliozoan eukaryotes in the order Desmothoracida, which are a group of organisms usually sessile and found in freshwater environments.
