Actinoscyphia

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

Characteristics

Actinostolidae with the pedal disc definite but sometimes very small and often embracing worm-tubes or needles of Hyalonema. Column thick to very thick, smooth. Tentacles arranged in two cycles at the margin of the wide oral disc, and provided with mesogloeal swellings at the bases of their outer sides. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. Sphincter mesogloeal, weak in comparison with the size of the body. Siphonoglyphs well developed. Mesenteries more numerous than tentacles. Six pairs of perfect and sterile mesenteries with diffuse retractors, other mesenteries, at least the older ones, fertile. Animals of fairly large size. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors.

About This Page
The information provided on this page is based on Oscar Carlgren's 1949 catalog.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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