The phylum Cnidaria: A review of phylogenetic patterns and diversity 300 years after Linnaeus
This work contrasts the Linnaean perspective on cnidarian diversity with the modern, phylogenetic perspective, and details diversity at the family level, providing phylogenetic context where possible. Expand
Hidden among Sea Anemones: The First Comprehensive Phylogenetic Reconstruction of the Order Actiniaria (Cnidaria, Anthozoa, Hexacorallia) Reveals a Novel Group of Hexacorals
Based on the comprehensive phylogeny, a new formal higher-level classification is proposed for Actiniaria composed of only two suborders, Anenthemonae and EnthemonAE and erect subgroups within these two newly-erected suborders. Expand
Gastrulation in the cnidarian Nematostella vectensis occurs via invagination not ingression.
Endodermal cells constrict their apices, adopting bottle-like morphologies especially pronounced adjacent to the blastopore lip during gastrulation, and injection of splice-blocking morpholinos to Nematostella snail genes does not result in a phenotype despite dramatically reducing wild-type transcript.

Systematics of the Hexacorallia (Cnidaria: Anthozoa)
It is found that orders Actiniaria, Antipatharia, Ceriantharia, Corallimorpharia, Scleractinia, and Zoanthidea are monophyletic; CorallIMorpharia is most closely related to Scleractsinia. Expand
Echinoderm phylogeny including Xyloplax, a progenetic asteroid.
It is hypothesized that the unique morphology of Xyloplax evolved via progenesis--the truncation of somatic growth at a juvenile body plan but with gonadal growth to maturity, which means that the overall phylogeny of extant echinoderms remains sensitive to the choice of analytical methods, but the placement of XYLoplax as sister to pterasterid asteroids is unequivocal.

Phylogenetic relationships among sea anemones (Cnidaria: Anthozoa: Actiniaria).
It is determined that taxonomic groups based on the absence of features tend not to be recovered as monophyletic, but that at least some classical anatomical features define monophylettic groups. Expand
Toward a natural classification: phylogeny of acontiate sea anemones (Cnidaria, Anthozoa, Actiniaria)
The results of the phylogenetic analyses indicate that the diagnostic morphological characters used in the family‐level taxonomy of acontiate actiniarians such as the nematocysts of the acontia, the marginal sphincter muscle, and mesenteries divisible into macro‐ and micro‐cnemes, have to be revisited, as these features are highly homoplasious.

  • 1 September 2010
The carcinoecium and complex behavioral and anatomical features associated with the symbiosis are interpreted as having evolved at least twice within Hormathiidae and seem to be phylogenetically labile. Expand
Anatomy and Taxonomy of Three Species of Sea Anemones (Cnidaria: Anthozoa: Actiniidae) from the Gulf of California, Including Isoaulactinia hespervolita Daly, n. sp.
Three distinct species of actiniarians from the Gulf of California having a column densely covered with vesicles or verrucae are discerned, based on anatomy, coloration patterns, types of cnidae in the column, and habitat preferences. Expand
Phylogenomic Analyses Support Traditional Relationships within Cnidaria
Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not wellExpand
