Halcampaster teres Carlgren 1938

Containing group: Halcampidae


Halcampidae with smooth, cylindrical body without tenaculi, not divisible into regions. Sphincter very weak, mesogloeal, close to the tentacles. Tentacles more than 12. Longitudinal muscles of tentacles ectodermal. 2 weak but distinct siphonoglyphs. Mesenteries showing a distinct tendency to pentamerous arrangement, owing to the retardation of the development of a pair of the mesenteries of the first cycle on one side of the directive plane. Only 5 pairs of macrocnemes, the others microcnemes. Mesenteries somewhat more numerous than tentacles. Retractors of the macrocnemes very strong restricted, reniform to almost circumscribed. Parietal muscles not very strong. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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