Anasca

Anasca was a bryozoan sub-order under class Cheilostomida defined by the lack of an ascus in each zooid. It is no longer an accepted taxonomic grouping as it is considered a polyphyletic and/or paraphyletic grouping.[1] The group is now subdivided into the suborders Inovicellata, Scrupariina, Malacostega, and Flustrina.[1]
