Epiactis ritteri Torrey 1902

Please note: Epiactis ritteri 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: Actiniidae

Characteristics

Actiniidae with broad pedal disc. Column smooth in its upper part, in its lower, from the limbus upward, provided with transverse and longitudinal rows of low protuberances square at the base, very close-set, and provided with extraordinarily numerous nematocysts (probably atrichs). Sphincter circumscribed. Tentacles rather short, comparatively numerous, as a rule arranged hexamerously. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. Usually two siphonoglyphs. Mesenteries for the most part perfect, and more numerous than the tentacles. Retractors not strong, parietobasilar and basilar muscles strong. Mesenteries of the first and second cycles probably sterile. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors (and probably atrichs).

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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