Collodaria is a unicellular order (organisms within the order are called Collodarians) under the phylum Radiozoa (or Radiolaria) and the infrakingdom Rhizaria. Like most of the Radiolaria taxonomy, Collodaria was first described by Ernst Haeckel, a German scholar who published three volumes of manuscript describing the extensive samples of Radiolaria collected by the voyage of HMS Challenger. Recent molecular phylogenetic studies concluded that Collodaria contains three families, Sphaerozodae, Collosphaeridae, and Collophidilidae.

== Story and origin == Ernst Haeckel is the main contributor to species description in the phylum Radiolaria, which contains the order Collodaria. Members of Collodaria were first described in 1862. In 1881, Collodaria was defined by Haeckel in 1881 as "Spumellaria without latticed shell."
