Containing group: Endomyaria


Carlgren's catalog (1949) recognized one genus of Minyadidae, Minyas, 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).


Minyadidae: Thenaria (Endomyaria) the base of which forms a float. It is hollowed out and has indrawn edges with only a slight opening (abnormally two), the cavity being filled by a chitinuous [sic], porous mass. Sphincter circumscribed. Tentacles simple or branched, arranged in radial series over the endocoels as from the exocoels. In very young specimens the arrangement of tentacles in rows is not conspicuous. Arrangement of mesenteries curious owing to the strong enlargement of the endocoels and strong diminution of the exocoels.

Minyas: Column smooth or with papillae in its upper part, with spirocysts. Fosse distinct. Sphincter weaker or stronger circumscribed. Tentacles short, papilliform, the exocoelic tentacles in a single row, the endocoelic tentacles may show a tendency to form two rows? Usually ten pairs of perfect mesenteries and ten pairs imperfect ones (sometimes some of the latter can reach the uppermost part of actinopharynx). The endocoels are strongly enlarged, the exocoels strongly reduced so that perfect and imperfect mesenteries lie close to each other in longitudinal furrows on the column and form secondary pairs with the retractors facing away from each other. Retractors strongly restricted, parietobasilar muscles broad but not folded. 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Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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 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.
