Containing group: Isophelliidae


Isophelliidae with small pedal disc and cylindrical, elongate body. Column divisible into scapus and scapulus, the former with tenaculi and cinclides. Sphincter mesogloeal, strong to fairly weak. Tentacles short, the inner longer than the outer, hexamerously arranged, more numerous than the mesenteries at the base. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. 2 narrow siphonoglyphs. Mesenteries divisible into macro- and microcnemes. The mesenteries of the first cycle and at least half the mesenteries of the second cycle are definite macrocnemes, the other of this cycle may be more or less marked macrocnemes, but with weaker retractors than the former. Each pair of the second cycle consists of a stronger and a weaker mesentery, all arranged in the same manner in relation to the directive plane. Retractors of the macrocnemes strong, restricted, with high folds. Parietal muscles weak to rather well developed, basilar muscles distinct. Mesenteries of the first cycle and at least the stronger ones of the second, fertile. Cnidom: spirocysts, basitrichs and probably microbasic p-mastigophors and microbasic amastigophors.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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