Choanophyta
Choanophyta, commonly known as choanoflagellates, are a group of free-living unicellular or colonial flagellate eukaryotes. They are predominantly aquatic, found in marine and freshwater environments worldwide. Their most distinctive feature is a single flagellum surrounded by a collar of microvilli. This collar is used for filtering food particles from the water, making choanoflagellates important consumers of bacteria and dissolved organic matter.
The structure of the choanoflagellate cell is highly specialized. The flagellum beats, creating a current that
Choanoflagellates exhibit diverse life cycles, often involving both asexual reproduction through budding or fission and sexual
