Acanthocorbis asymmetrica is a marine choanoflagellate, a unicellular organism closely related to the ancestors of animals, living in coastal and open ocean waters. Its cells are enclosed within a lorica (basket-like cage) constructed from siliceous costal strips that form an asymmetric pattern, distinguishing it from related species. It feeds on bacteria, playing a role in marine microbial food webs.
