Thalassianthidae
Characteristics
Thenaria (Endomyaria) with well developed base. Column with more or less distinct verrucae in its upper part. Sphincter weak, restricted or circumscribed. Oral disc sometimes thrown into numerous short, cyclically arranged, permanent lobes; or sometimes not. The lobes, when present, bear on the oral side dendritic tentacles which are continued on the disc and radially arranged, on the aboral side a group of nematospheres. At the margin a cycle of dendritic exocoelic tentacles. Longitudinal muscles of tentacles absent or very weak. 2 siphonoglyphs or several, the latter not connected with directives. Pairs of mesenteries numerous, many perfect, directives present or absent. Retractors well developed, diffuse, band-like. Parietobasilar muscles weak, basilar muscles well developed. Distribution of gonads varying, the mesenteries of the first cycle, apart from the directives, may be fertile. Cnidom: spirocysts, basitrichs, microbasic p-mastigophors.References

The information provided on this page is based on Oscar Carlgren's 1949 catalog.Copyright © 1949 Swedish Academy of Sciences.
Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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.
