The mitochondrial genome of basal animals is generally more slowly evolving than that of bilaterians. This difference in rate complicates the study of relationships among members of these lineages and the discovery of cryptic species or the testing of morphological species concepts within them. We explore the properties of mitochondrial and nuclear ribosomal genes in the cnidarian order Actiniaria, using both an ordinal- and familial-scale sample of taxa. Although the markers do not show… 
Linear Mitochondrial Genome in Anthozoa (Cnidaria): A Case Study in Ceriantharia
TLDR
The presence of tRNAMet and tRNATrp in both ceriantharian mitogenomes supports a closer relationship between Ceriantharia and Hexacorallia than between Ceria and any other cnidarian lineage, but phylogenetic analysis of the genes contained in the mitogenome suggests that Cerianstaria is sister to a clade containing Octocor allia indicating a possible suppression of tR NATrp.
Hidden among Sea Anemones: The First Comprehensive Phylogenetic Reconstruction of the Order Actiniaria (Cnidaria, Anthozoa, Hexacorallia) Reveals a Novel Group of Hexacorals
TLDR
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.
An EPIC journey to locate single‐copy nuclear markers in sea anemones
TLDR
EPIC (exon‐priming intron‐crossing) primers were employed to evaluate whether morphological variability in marginal tentacle protuberances is indicative of intraspecific variation or cryptic species in the shallow‐water anemone Phymanthus crucifer and a review of putative single‐copy markers used in octocoral and scleractinian phylogenetics.
Mitogenomics suggests a sister relationship of Relicanthus daphneae (Cnidaria: Anthozoa: Hexacorallia: incerti ordinis) with Actiniaria
TLDR
15 newly-sequenced sea anemone mitochondrial genomes and a mitogenome-based phylogeny including all major cnidarian groups, sponges, and placozoans are presented and a moderately supported sister relationship between Relicanthus and the Actiniaria is revealed.
Diversity and Distribution of Actiniaria
Sea anemones (Order Actiniaria) are among the most well successful groups of animals on the planet. They are distributed along the entire planet in several environments, from pole to pole, and so
Conspicuous morphological differentiation without speciation in Anemonia viridis (Cnidaria, Actiniaria)
TLDR
This study assesses the species status of the three most commonly found morphs of Anemonia viridis by coalescent analyses, and checks for clonality amongst 80 individuals of A. viridis var.
Evolutionary Diversification of Banded Tube-Dwelling Anemones (Cnidaria; Ceriantharia; Isarachnanthus) in the Atlantic Ocean
TLDR
It is revealed that two different species exist in the Atlantic Ocean and genetic divergence within and between Ceriantharia species is more similar to that found in Medusozoa than Anthozoa and Porifera that have divergence rates similar to typical metazoans.
Correction: Evolutionary Diversification of Banded Tube-Dwelling Anemones (Cnidaria; Ceriantharia; Isarachnanthus) in the Atlantic Ocean
The use of molecular data for species delimitation in Anthozoa is still a very delicate issue. This is probably due to the low genetic variation found among the molecular markers (primarily
Species Delimitation in Sea Anemones (Anthozoa: Actiniaria): From Traditional Taxonomy to Integrative Approaches
TLDR
Current gaps in knowledge are discussed, some future directions on how to address the issue of species delimitation in the extremely polymorphic group of sea anemones are offered and genetic studies show that morphological convergences are also widespread among molecular phylogenies.

Phylogenetic relationships within the class Anthozoa (phylum Cnidaria) based on nuclear 18S rDNA sequences.
TLDR
The 18S rRNA gene has sufficient phylogenetic signal, however, to distinguish among the major groupings within the Class Anthozoa, and this information is used to suggest relationships for the enigmatic taxa Dactylanthus and Dendrobrachia.
The partial mitochondrial genome of Leiopathes glaberrima (Hexacorallia: Antipatharia) and the first report of the presence of an intron in COI in black corals
TLDR
The partial genome of the antipatharian Leiopathes glaberrima is presented and the first phylogenetic analyses including complete mitochondrial genomes of the five hexacorallian orders are performed, reporting for the first time the presence of an intron in COI in the an antipatharians mt genome.
Mitochondrial and Nuclear Genes Suggest that Stony Corals Are Monophyletic but Most Families of Stony Corals Are Not (Order Scleractinia, Class Anthozoa, Phylum Cnidaria)
TLDR
A more comprehensive analysis of Scleractinia and various outgroups, based on two mitochondrial genes and analyses of nuclear genes of a subset of taxa to test unexpected relationships, suggests a future of greater taxonomic stability.
Atypically low rate of cytochrome b evolution in the scleractinian coral genus Acropora
TLDR
The results indicate that the Acropora cytochrome b gene is evolving at least 10 – 20 times slower than the ‘standard’ vertebrate mtDNA clock and is one of the most slowly evolving animal mitochondrial genes described to date.
A phylogenetic study of the Anthozoa (phylum Cnidaria) based on morphological and molecular characters
TLDR
This study presents a different phylogeny of actiniarians from the earlier hypothesis of scleractinian ancestry, and the trees constructed from the molecular data, using neighbor-joining and maximum-likelihood methods are nearly congruent with the result from the total evidence.
Systematic relationships within the Anthozoa (Cnidaria: Anthozoa) using the 5'-end of the 28S rDNA.
TLDR
Parsimony analysis indicates that the Ceriantipatharia are most representative of the ancestral Anthozoa, and gives no support for Hand's hypothesis of scleractinian ancestry of actiniarians and corallimorphians.
Slow mitochondrial DNA sequence evolution in the Anthozoa (Cnidaria)
TLDR
Slow evolution and unique characteristics may be common in primitive metazoans, suggesting that patterns of mtDNA evolution in these organisms differ from that in other animal systems.
