Phyllodiscus semoni Kwietniewski 1897

Containing group: Aliciidae


Aliciidae with broad pedal disc. Column in its lowermost part smooth, above this a broad zone with thick stalked outgrowths more or less distinctly radially arranged, which are drawn out distally into several short branches. On the branches, and rarely on the stalks also are found hemispheric vesicles containing microbasic and macrobasic amastigophors. There are few, but branched bands of longitudinal endodermal muscles in the stalks. Upper part (capitulum) of the column short with ectodermal longitudinal muscles. Sphincter indistinct, diffuse. Margin tentaculate. Tentacles numerous (up to about 160), hexamerously arranged with small stinging spots. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. 2 rather weak siphonoglyphs. 6 pairs of perfect and sterile mesenteries. Retractors diffuse, weak. Basilar muscles rather well developed. Gonads from the mesenteries of second cycle. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors, microbasic and macrobasic amastigophors.

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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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