RM2A2M9MM–Clathrulina elegans, Print, 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
RF2BT3PKD–Acanthocystis. Coloured scanning electron micrograph (SEM) of a centrohelid heliozoan with tangential plate-scales and radial spines. This genus Acanthocystis contains unicellular, free-floating planktonic or benthonic living organisms which are common in freshwater but also found more rarely in marine habitats. The evolutionary position of the centrohelids is not clear. Magnification: x 2500, when printed 10 centimetres wide.

Not only did this heliozoan feed upon Blepharisma but it did so voraciously and individuals of the latter were not only engulfed but digested. Almost as soon as a suspension of Blepharisma was added some were caught in the extended axopodia of the heliozoan. Sometimes on struggling they succeeded in breaking loose, but more often they did not. Within a few minutes they were engulfed in the streaming protoplasm and enclosed in a vacuole w
