Mercer R. Brugler, Corresponding Author. Mercer R. Brugler.DNA barcoding has been successfully applied to a very large number of taxa, but remains problematic for basal diploblasts, and debates about suitable molecular markers are ongoing. Sea anemones (Anthozoa: Hexacorallia: Actiniaria) populate most any marine environment and often play an irreplaceable role as hosts to other animals. Three genetic markers were tested to assess their utility for ...Zoantharia (Hexacorallia) is an order of benthic cnidarians, which are known to play an important ecological role in many marine ecosystems.

Introduction to the Octocorallia. Although commonly called "soft corals," the Octocorallia are not close relatives of the Scleractinia, or "true corals" living today.Unlike true corals, which have hexaradial symmetry, octocorals have eightfold radial symmetry -- count the tentacles on the polyps of this Muricea, from the Bahamas.

Several recent molecular phylogenetic studies of class Anthozoa using 18S rDNA or 16S mtDNA sequences have supported the monophyly of Octocorallia and have divided the sub-class into either two or three distinct clades (France et al., 1996, Berntson et al., 1999, Berntson et al., 2001, Won et al., 2001, Sánchez et al., 2003a).The most taxonomically comprehensive of these studies found support ...Sympatric diversification is recognized to have played an important role in the evolution of biodiversity. However, an in situ sympatric origin for codistributed taxa is difficult to demonstrate because different evolutionary processes can lead to similar biogeographic outcomes, especially in ecosystems that can readily facilitate secondary contact due to a lack of hard barriers to dispersal.

Hexacorallia ou Hexacoralla é uma importante subclasse dos antozoários. A subclasse dos Zoantharia (do grego zoon , animal + anthos , flor + aria , como ou conectado com) não é mais que esta mesma subclasse, à qual se acrescentam as ordens Rugosa e Cerantipitharia . Within Anthozoa, the monophyly of Hexacorallia has low support due to the phylogenetic instability of Ceriantharia (Fig 4, S1 and S2 Figs), our most poorly sampled taxon within Anthozoa (16.6% gene sampling). Each analysis provides mixed support for the placement of Ceriantharia as either sister to the rest of the Hexacorallia, ...Jan 11, 2021 · The process of calcium carbonate biomineralization has arisen multiple times during metazoan evolution. In the phylum Cnidaria, biomineralization has mostly been studied in the subclass Hexacorallia (i.e. stony corals) in comparison to the subclass Octocorallia (i.e. red corals); the two diverged approximately 600 million years ago. The …Antipatharians, also known as black corals, represent a small group of anthozoan hexacorallians found in all oceans of the world.

It includes groups like Zoanthids, Sea Anemones, and Corallimorpharians . They are carnivores. They have sexual reproduction and asexual reproduction. Using scanning and transmission electron microscopy, we discover a third apical morphology in nematocysts, an apical cap, which we find in all nonactiniarian anthozoans examined. This apical cap is identical structurally to the apical cap of spirocysts, and it resembles the apical structure of ptychocysts, whose apex is documented here for the ...

We present the complete genome sequences of 7 species of the zoantharian genus Epizoanthus . Illumina sequencing was performed on genetic material from single wild-collected individuals. The reads were assembled using a de novo method followed by a finishing step. The raw and assembled data ar …The ecological success of shallow-water reef-building corals (Hexacorallia: Scleractinia) is framed by their intimate endosymbiosis with photosynthetic dinoflagellates in the genus Symbiodinium (zooxanthellae). In contrast, the closely related black corals (Hexacorallia: Anthipatharia) are described as azooxanthellate (lacking Symbiodinium), a trait thought to reflect their preference for low ...Taxonomic status of the zoanthid genera Palythoa and Protopalythoa has been in question for almost a century.
