This supergroup was proposed by ] in 2002. Being described mainly from ] sequences, they vary considerably in form, having no clear morphological distinctive characters (]), but for the most part they are ]s with filose, reticulose, or microtubule-supported ]s. The Rhizaria’s pseudopodial mineral skeleton network, which is made up of opal (SiO₂), celestite (SrSO₄), or calcite (CaCO₃), is what differentiates it from the amoebae. It can attain sizes of more than a centimeter with some species being able to form cylindrical colonies approximately 1 cm in diameter and greater than 1 m in length. They feed by capturing and engulfing prey within the extensions of their pseudopodial skeletons, and some even become homes for algae, which aid in boosting the total primary production of the ocean.<ref>Caron, D. (2016). The rise of Rhizaria. Nature (London), 532(7600), 444–445. https://doi.org/10.1038/nature17892</ref> |

A few other groups may be included in the Cercozoa, but some trees appear closer to the Foraminifera. These are the Phytomyxea and Ascetosporea, parasites of plants and animals, respectively, and the peculiar amoeba Gromia. The different groups of Rhizaria are considered close relatives based mainly on genetic similarities, and have been regarded as an extension of the Cercozoa. The name Rhizaria for the expanded group was introduced by Cavalier-Smith in 2002, who also included the centrohelids and Apusozoa.
In 2019, the Cercozoa were recognized as a basal Rhizaria group, as sister of the Retaria.
