This protist belongs to the supergroup Rhizaria, which is a phylum as species rich as plants, but of which there are only three genomes available yet! R. pseudocylindrica is very small and admittedly not a beauty, but environmental surveys report occasional huge abundances in limnic, terrestrial and even aerial habitats. There it is an important consumer of bacteria and other microbes. This specie's ambassador is Kenneth Dumack. Conducted by worm~lab and West German Genome Center.
