Abstract: Hydromedusae were photographed and collected during 75 night-time dives in the Gulfstream off Florida. Most of the collected material was used to obtain DNA extracts and subsequently to determine part of the mitochondrial 16S rRNA gene, a barcode marker preferentially used for hydrozoans. The morphological data and the 16S barcodes permitted us to identify 46 species and 6 additional species nameable only to the genus level. Photos and descriptions are provided for all of them and the… 
Integrative systematics illuminates the relationships in two sponge-associated hydrozoan families (Capitata: Sphaerocorynidae and Zancleopsidae)
An integrated approach using morphological and genetic data is used to accurately characterise species in these families, identify the previously unknown polyp stages of the genera Euphysilla and Zancleopsis, describe a new sphaerocorynid genus and species, and assess the phylogenetic position of the two families within the Capitata.


Some shallow-water hydroids (Cnidaria: Hydrozoa) from the central east coast of Florida, USA.
This paper gives a systematic account of 67 species, referable to 22 families and 40 genera, identified in a small collection of hydroids from the central Atlantic coast of Florida between Melbourne
Gelatinous zooplankton net-collected in the Gulf of Maine and adjacent submarine canyons: new species, new family (Jeanbouilloniidae), taxonomic remarks and some parasites
A systematic account is provided of the siphonophores, medusae, ctenophores, molluscs and salps net-collected in basins of the Gulf of Maine and adjacent canyons during three cruises carried out in
Faunistic survey of Hydromedusae (Cnidaria, Medusozoa) from the coast of Paraná State, Southern Brazil.
This study is the first faunistic inventory of hydromedusae from the inner continental shelf of Paraná State, and finds the first record of Bougainvillia frondosa, Ectopleura dumortieri, Cirrholovenia tetranema, Eucheilota maculata, Gossea brachymera, Solmaris corona, and Amphogona apsteini.
Census of Cnidaria (Medusozoa) and Ctenophora from South American marine waters.
This census compiled available records in the literature for medusozoan cnidarians and ctenophores of South America includes a synonymy list for South America, taxonomical remarks, notes on habit, and information on geographical occurrence.
On a collection of hydroids (Cnidaria, Hydrozoa) from the southwest coast of Florida, USA.
The fauna studied here consists largely of species known to occur in the tropical and subtropical western Atlantic, and topotypic specimens from the Chesapeake Bay region are illustrated to document characters that distinguish the species.
Hydroid diversity of Eilat Bay with the description of a new Zanclea species
The present investigation provides new information about diversity in the Red Sea, and in particular in Eilat Bay, which has significance for Mediterranean and Red Sea biodiversity conservation and the consequent possible increase in the introduction of nonindigenous species in both directions.
Additional shallow-water thecate hydroids (Cnidaria: Hydrozoa) from Guadeloupe and Les Saintes, French Lesser Antilles
The number of hydroid species reported from the study area is raised to more than eighty, though continuous discovery of new species is likely, the species composition being certainly richer than currently reported.
New additions to the hydroids (Cnidaria: Hydrozoa) from the fjords region of southern Chile
Eleven species of thecate hydroids collected during a recent scientific expedition to the North Patagonian Zone between southern Chiloe and Puyuguapi fjord/ Magdalena Island are reported upon.
An integrative identification guide to the Hydrozoa (Cnidaria) of Bocas del Toro, Panama
ABSTRACT This work is the first attempt to assess the biodiversity of the Hydrozoa in the Archipiélago de Bocas del Toro (Panamá, Caribbean Sea) using morphology and molecular taxonomy, and to
DNA barcoding reveals cryptic diversity in marine hydroids (Cnidaria, Hydrozoa) from coastal and deep‐sea environments
The mitochondrial 16S rRNA proved to be a useful DNA ‘barcode’ gene for hydroids, not only allowing discrimination of species, but also in some cases of populations, genera and families, and their intra‐ or interphylogenetic associations.
