1. (class Turbellaria, subclass Archoophora) An order of platyhelminth worms (Platyhelminthes) that have no gut cavity or pharynx.
2. (class Gastropoda, subclass Opisthobranchia) An order of molluscs that possess no shell, mantle cavity, or gills. Respiration is carried out by branchiae. Dorsal outgrowths are quite common, and all have undergone complete detorsion. Benthic and planktonic forms occur. There is only one fossil family recorded, which appeared in the Eocene. According to some authorities, the taxonomic use of ‘Acoela’ as a molluscan order should be discouraged. It represents an attempt to unite the Notaspidea and Nudibranchia.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
