Please note: Entries in the above species list are the original binomina of species according to Carlgren's 1949 catalog. Nomenclatorial inconsistencies need to be resolved in a future revision of this genus (see below).
Containing group: Actinostolidae


Actinostolidae with broad base. Column smooth, variable in thickness, margin tentaculate. Sphincter mesogloeal strong so that the upper part of the body can cover the tentacles. Tentacles short, conical, fairly numerous without mesogloeal thickenings on their outer sides, with large microbasic b-mastigophors in their distal parts. Longitudinal muscles of tentacles mesogloeal to ecto-mesogloeal, radial muscles of oral disc mesogloeal. 2 well developed siphonoglyphs. Tentacles and pairs of mesenteries frequently arranged 16 (6+10), 16, 32; 16-18 pairs perfect. Perfect mesenteries generally sterile but when the perfect pairs are more than 16 the exceeding pairs are often fertile, at least the stronger imperfect mesenteries fertile. Considerably more mesenteries at the base than at the margin. In the youngest cycles the mesenteries of one and the same pair are unequally developed in such a way that the partner furthest away from the adjacent mesenterial pair of the next oldest cycle is the larger (as in Actinostola). Retractors diffuse, well developed, parietobasilar and basilar muscles strong. Cnidom: spirocysts, basitrichs, microbasic b- and p-mastigophors.

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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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 Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, 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.
