Isadamsia cancrisocia Carlgren 1928

Containing group: Actiniidae


Actiniidae with very wide pedal disc forming a cuticle which may project beyond the mouth of the shell to which it is fastened. Column smooth, without cinclides. Sphincter circumscribed. Tentacles short, hexamerously arranged, somewhat fewer than the mesenteries at the base. Longitudinal muscles of tentacles and radial muscles of oral disc ectodermal. Mesenteries numerous, several cycles of perfect mesenteries. Mesenteries of the three first cycles sterile. Retractors weak, diffuse, parietobasilar and basilar muscles distinct. The species of the genus live in symbiosis with hermit crabs in such a way that their mouths are always situated beneath that of the hermits (as in Adamsia). No acontia.

Please note that Carlgren's text contains a number of errors, and much of the information is now out of date.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