Containing group: Haliactiidae


Haliactiidae with very elongate, vermiform body. Column divisible into physa, scapus and capitulum or not. Capitulum with spirocysts, scapus with longitudinal rows of stinging warts or spots. Cinclides in the upper part of the column, arranged in longitudinal rows. No distinct sphincter. Uppermost part of the capitulum and the oral disc thrown out into 6 long outgrowths or pedicels each bifurcating two or three times. Most of tentacles placed in groups at the distal end of the pedicels. Actinophorynx [sic] long. 2 siphonoglyphs. Mesenteries divisible into macro- and microcnemes. Macrocnemes 6 pairs, microcnemes in several cycles. Mesenteries more numerous distally than proximally. Retractors of macrocnemes reniform to more diffuse. Parietal muscles rather weak to weak. Acontia long but slender, with basitrichs and microbasic amastigophors? (penicilli). Cnidom: spirocysts, basitrichs, microbasic amastigophors? and probably 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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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 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.
