Choanoflagellatea
Sign in to saveAlso known as Choanoflagellata, Choanomonada, Choanoflagellate
Choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of animals. The name refers to the characteristic funnel-shaped "collar" of interconnected microvilli and the presence of a flagellum. Choanoflagellates are found globally in aquatic environments, and they are of particular interest to evolutionary biologists studying the origins of multicellularity in animals.
OverviewAI-generated
Choanoflagellatea is a class of organisms within the phylum Choanozoa. It is also classified under the kingdom Protozoa and the parent taxa Holozoa and Choanozoa. The class was described by Cavalier-Smith in 1998 and holds an accepted taxonomic status. Common names for this group include choanoflagellates, 立襟鞭毛綱, 领鞭毛纲, and 襟鞭毛虫綱.
The habitat of Choanoflagellatea includes marine, brackish, and freshwater environments. Records of this taxon are documented in sources such as the Granat Encyclopedic Dictionary and the Brockhaus and Efron Encyclopedic Dictionary.

Choanoflagellates are a group of free-living unicellular and colonial flagellate eukaryotes considered to be the closest living relatives of animals. The name refers to the characteristic funnel-shaped "collar" of interconnected microvilli and the presence of a flagellum. Choanoflagellates are found globally in aquatic environments, and they are of particular interest to evolutionary biologists studying the origins of multicellularity in animals.
The flagellum of choanoflagellates is surrounded by microvilli at its base. Movement of the flagellum creates water currents that can propel free-swimming choanoflagellates through the water column and trap bacteria and detritus against the microvilli, where these foodstuffs are engulfed. This feeding plays an ecological role in the carbon cycle by linking different trophic levels.
