Heteractis

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: Aiptasiidae

Characteristics

Aiptasiidae with distinct base. Column smooth, with cinclides in a horizontal zone near the middle of the column. Margin tentaculate. Sphincter weak, mesogloeal. Tentacles up to 192 in number, not fully retractile with scattered, spherical, hollow protuberances on their surface, differing from the rest of the tentacle chiefly in that they possess many nematocysts and have reduced longitudinal muscles. Longitudinal muscles of tentacles ectodermal. Oral disc not lobed. Six pairs of perfect and fertile mesenteries, 2 pairs of directives. Probably more mesenteries distally than proximally. Retractors diffuse, parietobasilar muscles weak. Acontia numerous. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors, microbasic amastigophors.

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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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