Actinia prolifera M. Sars 1835

Please note: Actinia prolifera is the original binomen of this species according to Carlgren's 1949 catalog. Nomenclatorial inconsistencies need to be resolved in a future revision of this genus (see below).
Containing group: Protantheae


Gonactiniidae with smooth, cylindrical body. Margin not undulated. Column with well developed longitudinal muscles and nerve-stratum. Tentacles rather long, few, not constricted at their base, not swollen at the apex. Usually 8 mesenteries perfect but in connection with reproduction by transverse fisison [sic] the number of perfect mesenteries may be a little irregular. Imperfect mesenteries 8, four forming pairs with the perfect mesenteries, and four forming two pairs in the dorsolateral exocoels. Only the lateral perfect mesenteries fertile, the perfect mesenteries and sometimes the fifth couple with filaments. Longitudinal muscles of the mesenteries and the parietobasilar muscles weak. Reproduction by transverse fission. Cnidom: see the family.

About This Page
The information provided on this page is based on Oscar Carlgren's 1949 catalog.
Copyright © 1949 Swedish Academy of Sciences.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date. An update of the catalog is currently under preparation in Daphne Fautin's laboratory, and the results of this work will be incorporated in future versions of this page.

Keyboarding of Carlgren's catalog was done as part of a project to create an electronic database of the sea anemones of the world, funded by NSF Grant DEB9521819, awarded to Daphne G. Fautin. This grant is in the program Partnerships to Enhance Expertise in Taxonomy (PEET). Susanne Hauswaldt, Katherine Pearson, and April Wakefield-Pagels contributed to the keyboarding effort.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
