Fast-evolving mitochondrial DNA in Ceriantharia: a reflection of hexacorallia paraphyly?

PLoS ONE, 2014
The low evolutionary rate of mitochondrial genes in Anthozoa has challenged their utility for phylogenetic and systematic purposes, especially for DNA barcoding.

New Records of Cold-Water Corals from Korea [PDF]

Animal Systematics, Evolution and Diversity, 2016
Two cold-water coral taxa, Octocorallia in the class Anthozoa and Stylasteridae in the class Hydrozoa, were identified. Deep-water samples were collected in fishing nets at depths ranging between 20 and 200 m along the coasts of the East Sea in Korea ...

Deciphering the evolutionary history of early Mesozoic fossil corals [PDF]

Acta Palaeontologica Polonica
The morphology of stony corals (Scleractinia) remains the only means to reconstruct the most inclusive evolutionary history of the clade comprising both extant and extinct species.

Evolution of bioluminescence in Anthozoa with emphasis on Octocorallia. [PDF]

Proc Biol Sci
Bioluminescence is a widespread phenomenon that has evolved multiple times across the tree of life, converging among diverse fauna and habitat types. The ubiquity of bioluminescence, particularly in marine environments where it is commonly used for communication and defense, highlights the adaptive value of this trait, though the evolutionary origins ...

Anticancer Potential of Piericidin A1 and Derivatives Isolated From Streptomyces sp. Associated With Palythoa variabilis From Brazilian Reefs. [PDF]

Chem Biodivers
A Streptomyces spp. strain, isolated from the zoantharian Palythoa variabilis, produces the complex I mitochondrial inhibitor piericidin A1 with effects on cancer cells proliferation and MTT‐formazan reduction at concentrations up to 0.1 aM. ABSTRACT Marine holobionts are an important source of bioactive natural products.

Cnidarian Interaction with Microbial Communities: From Aid to Animal’s Health to Rejection Responses

Marine Drugs, 2018
The phylum Cnidaria is an ancient branch in the tree of metazoans. Several species exert a remarkable longevity, suggesting the existence of a developed and consistent defense mechanism of the innate immunity capable to overcome the potential repeated ...

Cnidarian Pattern Recognition Receptor Repertoires Reflect Both Phylogeny and Life History Traits

Frontiers in Immunology, 2021
Pattern recognition receptors (PRRs) are evolutionarily ancient and crucial components of innate immunity, recognizing danger-associated molecular patterns (DAMPs) and activating host defenses.

Accounting for Intra- and Intergenomic Sequence Variation in Reference Barcodes Improves eDNA Metabarcoding Biodiversity Assessment. [PDF]

Mol Ecol Resour
ABSTRACT Environmental DNA (eDNA) metabarcoding can rapidly characterise biodiversity, yet its accuracy and effectiveness are limited by incomplete DNA barcode reference databases. We evaluated how comprehensive reference databases that include sequence variation within genomes (intragenomic) and across individuals and species (intergenomic) improve ...

A Review of Toxins from Cnidaria

Marine Drugs, 2020
Cnidarians have been known since ancient times for the painful stings they induce to humans. The effects of the stings range from skin irritation to cardiotoxicity and can result in death of human beings.

A New Record of Dendrophyllia compressa (Anthozoa: Hexacorallia: Scleractinia: Dendrophylliidae) from Korea [PDF]

Animal Systematics, Evolution and Diversity, 2016
Dendrophyllia compressa Ogawa and Takahashi, 1995 is newly reported from Korea. The specimen was collected off Seogwipo, Jeju-do, Korea in 1969. It is described herein based on the morphological characters of the skeletal structures.
