Containing group: Acontiaria


Carlgren's catalog (1949) recognized one genus of Aiptasiomorphidae, Aiptasiomorpha, containing five species. The names listed above are the original binomina of these species. Nomenclatorial inconsistencies need to be resolved in a future revision of this genus (see below).


Aiptasiomorphidae: Thenaria (Acontiaria) with no sphincter or a weak endodermal one. Never atrichs, holotrichs and macrobasic amastigophors in the tentacles. Acontia with basitrichs and microbasic p-mastigophors?

Aiptasiomorpha: Aiptasiomorphidae with distinct pedal disc. Column varying from low to pillarlike or trumpetshaped, divided into scapus and capitulum. The scapus ends above in a fold or collar, from within which arises the delicate capitulum. Margin of capitulum tentaculate. Cinclides present. Sphincter absent or weak endodermal. Tentacles smooth, retractile or not, their longitudinal muscles ectodermal. Typically six pairs of perfect mesenteries, which may be fertile; but in forms with asexual reproduction the arrangement of mesenteries is very variable, the siphonoglyphs and pairs of directives varying from 1 to 5, and the numbers of pairs of perfect mesenteries at least from 5 to 12. Mesenteries more numerous distally than proximally (?always). Retractors more or less restricted. Acontia with basitrichs and 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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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.
