Revision of the genus Chrysaora Peron & Lesueur, 1810 (Cnidaria: Scyphozoa)
The phylogenetic hypothesis indicates that the genus Chrysaora forms a monophyletic group, with C. achlyos having a basal position in the phylogeny.

It is concluded that blooms may be defined phylogenetically by the specific asexual modes each species develops, which, in turn, is regulated by environmental conditions.

This chronicle the arrival of jellyfish fisheries in the Americas and summarize relevant information on jellyfish fishing, processing, and management is summarized.
Characterizations of juvenile stages of some semaeostome Scyphozoa (Cnidaria), with recognition of a new family (Phacellophoridae)
Early stages of Phacellophora camtschatica of the species were compared with those of several other semaeostomes currently assigned to Ulmaridae, Pelagiidae, and Cyane families, and Juveniles of P. camts chatica did not strictly conform with characters of those of any of these families.
The life cycle of Chrysaora lactea Eschscholtz, 1829 (Cnidaria, Scyphozoa) with notes on the scyphistoma stage of three other species
The life cycle of Chrysaora lactea Eschscholtz, 1829, a common species on the Brazilian coast, is described and ephyrae and young medusae were maintained in laboratory conditions up to 7 months.
Proteomic characterisation of toxins isolated from nematocysts of the South Atlantic jellyfish Olindias sambaquiensis.
All non-indigenous species were introduced recently? The case study of Cassiopea (Cnidaria: Scyphozoa) in Brazilian waters

Genetic sequence data indicate that the Brazilian jellyfishes are genetically similar to those from Bermuda, Hawaii and Florida, which are related to specimens from the Red Sea (Cassiopea and Andromeda), and it is hypothesized that the presence of C. and Andromeda in Brazil is due to an invasion event.
Fast-Evolving Mitochondrial DNA in Ceriantharia: A Reflection of Hexacorallia Paraphyly?
A pattern of divergence of mitochondrial DNA completely different from those estimated for other anthozoans is demonstrated, and phylogenetic analyses indicate that Ceriantharia is not included within hexacorallians in most performed analyses, and it is proposed that the Cerantharia should be addressed as a separate clade.
Food web characterization based on δ15N and δ13C reveals isotopic niche partitioning between fish and jellyfish in a relatively pristine ecosystem
Describing isotopic niche breadth, position, and overlaps provides a general picture of trophic roles, interactions and the degree of functional redundancy among species, allowing an evaluation of possible directions of community shifts resulting from the removal or proliferation of keystone consumers.
