Containing group: Endocoelantheae

Characteristics

Endocoelantheae with the thick body usually expanded above and then drawn out into lobes which are typically 4 or 8 in number. Sometimes there are small nematocyst batteries in the ectoderm of the column. Tentacles numerous, simple, or thickened on their aboral sides, 2 siphonoglyphs. Mesenteries numerous, not divisible into macro- and microcnemes, many are perfect. The later ones are arranged either cyclically or bilaterally, and the partners of a pair may be equal or unequal. Retractors weak. All stronger mesenteries fertile.

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.
