A stable phylogenetic hypothesis for families within jellyfish class Scyphozoa has been elusive. Reasons for the lack of resolution of scyphozoan familial relationships include a dearth of morphological characters that reliably distinguish taxa and incomplete taxonomic sampling in molecular studies. Here, we address the latter issue by using maximum likelihood and Bayesian methods to reconstruct the phylogenetic relationships among all 19 currently valid scyphozoan families, using sequence data…

New Family of Allomorphic Jellyfishes, Drymonematidae (Scyphozoa, Discomedusae), Emphasizes Evolution in the Functional Morphology and Trophic Ecology of Gelatinous Zooplankton

This family-level revision contributes to the growing body of evidence that scyphomedusae are far more taxonomically rich, their biogeography is a more detailed mosaic, and their phenotypes are more nuanced than traditionally thought.

Redescription of Pelagia benovici into a new jellyfish genus, Mawia, gen. nov., and its phylogenetic position within Pelagiidae (Cnidaria : Scyphozoa : Semaeostomeae)

Comprehensive morphological analyses of diagnostic characters revealed significant differences from the currently known genera Sanderia, Chrysaora and Pelagia in the family Pelagiidae, and a new genus Mawia, gen. nov. (Semaeostomeae : Pelagiidae) is described, and Pelgia benovici is renamed.

Cnidarian phylogenetic relationships as revealed by mitogenomics

These analyses suggest that the shared morphological characters in these groups are plesiomorphies, originated in the branch leading to Medusozoa, and the hypothesis that Staurozoa is the sister group to all the other medusozoans is rejected.

The importance of molecular characters when morphological variability hinders diagnosability: systematics of the moon jellyfish genus Aurelia (Cnidaria: Scyphozoa)

It is demonstrated that morphological variability in Aurelia medusae overlaps across very distant geographic localities, and clarifies the practical implications of molecular genetic data as diagnostic characters, and sheds light on the patterns and processes that generate crypsis.

Versuriga anadyomene, a newly recorded scyphozoan jellyfish (Scyphozoa: Rhizostomae) in Chinese waters

The rhizostome jellyfish found in Beibu Gulf, South China Sea, on 27 May 2015 was the first record of the genus Versuriga and the species V. anadyomene in Chinese seas and may be attributed to physical transport from the coastal waters of South East Asia.

Unmasking Aurelia species in the Mediterranean Sea: an integrative morphometric and molecular approach

Molecular analyses have led to an increased knowledge of the number and distribution of morphologically cryptic species in the world's oceans and, concomitantly, to the identification of

Species richness of jellyfishes (Scyphozoa : Discomedusae) in the Tropical Eastern Pacific: missed taxa, molecules, and morphology match in a biodiversity hotspot

The need to evaluate the evolutionary relationships with neighbouring regions to understand fully the origins of jellyfish diversity in the TEP is understood and will lead to revision of the systematics and taxonomy of Scyphozoa.

Multigene phylogeny of the scyphozoan jellyfish family Pelagiidae reveals that the common U.S. Atlantic sea nettle comprises two distinct species (Chrysaora quinquecirrha and C. chesapeakei)

A paraphyletic Chrysaora raises systematic questions at the genus level for Pelagiidae; accepting the validity of the recently erected genus Mawia, as well as past genera, will require the creation of additional pelagiid genera.

First record of Aequorea macrodactyla (Cnidaria, Hydrozoa) from the Israeli coast of the eastern Mediterranean Sea, an alien species indicating invasive pathways.

The results indicate introduction from the Indo-Pacific as invasive pathway, probably by human transportation, and the discovery of A. macrodactyla in the eastern Mediterranean Sea could be interpreted as part of the changes in marine biota as a result of cumulative effects of anthropogenic and global changes that affect theEastern Mediterranean basin.

Origin and early diversification of the phylum Cnidaria Verrill: major developments in the analysis of the taxon's Proterozoic–Cambrian history

Diploblastic eumetazoans of the phylum Cnidaria originated during the Neoproterozoic Era, possibly during the Cryogenian Period. The oldest known fossil cnidarians occur in strata of Ediacaran age



Some implications of molecular phylogenetics for understanding biodiversity in jellyfishes, with emphasis on Scyphozoa

Results highlight difficulties with traditional morphological treatments including terminology that obfuscates homologies and suggest a much richer understanding of the biodiversity and evolution of jellyfishes is achievable by integrating molecular phylogenetic analyses with old and new morphological, behavioural, developmental, physiological, and other data.

Reassessment of the phylogenetic position of conulariids (?Ediacaran‐Triassic) within the subphylum medusozoa (phylum cnidaria)

Conulariids are the sister group of the scyphozoan order Coronatae rather than Stauromedusae, which is revealed as the earliest diverging lineage of Medusozoa, and this new hypothesis implies several different sequences of character evolution within Cnidaria.

Medusozoan phylogeny and character evolution clarified by new large and small subunit rDNA data and an assessment of the utility of phylogenetic mixture models.

A newly compiled data set of nearly complete sequences of the large subunit of the nuclear ribosome (LSU or 28S) sampled from 31 diverse medusozoans greatly clarifies the phylogenetic history of

A preliminary phylogeny of Pelagiidae (Cnidaria, Scyphozoa), with new observations of Chrysaora colorata comb. nov.

The nomenclature of the purple-striped jellyfish from southern California, currently known as Pelagia colorata Russell, 1964, is apparently in error. Our cladistic analysis of 20 characters for 15

Molecular Evidence for Cryptic Species of Aurelia aurita (Cnidaria, Scyphozoa)

Nuclear and mitochondrial DNA sequence data indicate speciation events as early as the late Cretaceous or early Tertiary, consistent with the formation of well-recognized biogeographic barriers to gene flow in the seas.

Phylogeny of the Lemuridae: Effects of Character and Taxon Sampling on Resolution of Species Relationships within Eulemur☆

It is found that the combined genetic data set is more robust to changes in taxon sample than are any of the individual data sets, suggesting that increased character sampling stabilizes phylogenetic resolution.

Cladistic analysis of Medusozoa and cnidarian evolution

A cladistic analysis of 87 morphological and life history characters of medusozoan cnidarians, rooted with Anthozoa, results in the phylogenetic hypothesis (Anthozoa (Hydrozoa (Scyphozoa) (StaurozoA, Cubozoa))) and a phylogenetic classification of Medusozoa that is consistent with phylogenetic hypotheses based on cladistic results, as well as those derived from 18S analyses.

Global phylogeography of Cassiopea (Scyphozoa: Rhizostomeae): molecular evidence for cryptic species and multiple invasions of the Hawaiian Islands

Molecular phylogenetic results support at least two independent introductions to the Hawaiian Islands, one from the Indo-Pacific, another from the western Atlantic/Red Sea, and two deeply divergent O’ahu haplotypes from morphologically similar, geographically separate invasive populations indicate long-term reproductive isolation of phylogenetically distinct source populations and cryptic species.

Resolving arthropod phylogeny: exploring phylogenetic signal within 41 kb of protein-coding nuclear gene sequence.

This study attempts to resolve relationships among and within the four basal arthropod lineages and to assess the widespread expectation that remaining phylogenetic problems will yield to increasing amounts of sequence data.

Macro-morphological variation among cryptic species of the moon jellyfish, Aurelia (Cnidaria: Scyphozoa)

It is shown that Aurelia aurita is most likely endemic to the boreal Atlantic Ocean and northern European seas, Aurelia labiata is neither as morphologically diverse nor widespread as recently described, and the circumglobal Aurelia sp.
