In the classification of eukaryotes (living organisms with a cell nucleus), Cabozoa was a taxon proposed by Cavalier-Smith.{{cite journal |author=Cavalier-Smith T |title=Principles of protein and lipid targeting in secondary symbiogenesis: euglenoid, dinoflagellate, and sporozoan plastid origins and the eukaryote family tree |journal=J. Eukaryot. Microbiol. |volume=46 |issue=4 |pages=347–66 |year=1999 |pmid=18092388 |doi= 10.1111/j.1550-7408.1999.tb04614.x|s2cid=22759799 }} It was a putative clade comprising the Rhizaria and Excavata. More recent research places the Rhizaria with the Alveolata and Stramenopiles instead of the Excavata, however, so "Cabozoa" is polyphyletic.{{cite journal | vauthors = Burki F, Shalchian-Tabrizi K, Minge M, Skjæveland Å, Nikolaev SI | editor1-last = Butler | year = 2007 | editor1-first = Geraldine | title = Phylogenomics Reshuffles the Eukaryotic Supergroups | journal = PLOS ONE | volume = 2 | issue = 8: e790 | doi = 10.1371/journal.pone.0000790 | pages = e790 | pmid = 17726520 | pmc = 1949142|display-authors=etal| bibcode = 2007PLoSO...2..790B | doi-access = free }}{{Cite web |last=Zicha |first=Ondrej |title=BioLib: Biological library |url=https://www.biolib.cz/en/taxon/id322927/ |access-date=17 March 2023 |website=www.biolib.cz}}
