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: Sagartiidae


Sagartiidae with well developed base. Body sometimes divisible into scapus and scapulus, sometimes not. Scapus often but not necessarily with a cuticle and tenaculi which as a rule are weaker than in Kadosactis, sometimes they are reduced and not uncommonly absent. Column with cinclides in its upper part, usually near on the limbus. Margin distinct or tentaculate. Sphincter mesogloeal, well developed. Tentacles usually long, conical, hexamerously, octamerously, decamerously or irregularly arranged, never thickened on their aboral side. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. Usually two siphonoglyphs, sometimes only one, rarely three, 1-3 pairs of directives. As a rule at least 6 pairs of perfect mesenteries, usually more. Younger mesenteries growing from the limbus as well as from the margin, but originating somewhat earlier at the margin than at the limbus. Perfect and stronger imperfect mesenteries, in the region of the actinopharynx provided with fairly restricted, often kidney-shaped, rarely circumscribed retractors. Parietobasilar muscle not strong. All stronger mesenteries fertile. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors and microbasic 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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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 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.
