Antiparactis

Paractis lineolatus Mc Murrich [sic] 1893

Please note: Paractis lineolatus is the original binomen of this species according to Carlgren's 1949 catalog. Nomenclatorial inconsistencies need to be resolved in a future revision of this genus (see below).
Containing group: Actinostolidae

Characteristics

Actinostolidae with well developed pedal disc. Column smooth, without tubercles, in the contracted state low and thin and with more or less distinct longitudinal ridges in its uppermost part. Margin tentaculate, not lobed. Sphincter mesogloeal, strong. Tentacles short, without stinging-batteries. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. Actinopharynx long, with two siphonoglyphs. Mesenteries hexamerously arranged, twice as many as the tentacles. 6 pairs of perfect and sterile. Mesenteries of the second and third cycle fertile. No differentiation into filament-lacking fertile and filamented sterile mesenteries. Retractors diffuse, weak.

About This Page
The information provided on this page is based on Oscar Carlgren's 1949 catalog.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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