SAR supergroup
Encyclopedia
The SAR supergroup is a clade
that includes Stramenopiles (aka Heterokonts), Alveolates, and Rhizaria
.
The first letter of each group provides the "SAR" in the name.
It includes most of the organisms in the Chromalveolata grouping, but not Hacrobia
.
The term "Harosa" (at the subkingdom level) has also been used for this grouping.
Clade
A clade is a group consisting of a species and all its descendants. In the terms of biological systematics, a clade is a single "branch" on the "tree of life". The idea that such a "natural group" of organisms should be grouped together and given a taxonomic name is central to biological...

Rhizaria
The Rhizaria are a species-rich supergroup of unicellular eukaryotes. This supergroup was proposed by Cavalier-Smith in 2002. They vary considerably in form, but for the most part they are amoeboids with filose, reticulose, or microtubule-supported pseudopods...
