New species of Eirenidae (Hydrozoa: Leptothecata) from the Amazonian coast (northern Brazil) [PDF]
Two new Eirenidae medusae species were collected on the Amazonian coast, Eutima marajoara n. sp. and Helgicirrha angelicae n. sp. The former differs from other species of the genus by the gonads extending along almost the entire length of the ...

Diversity and life-cycle analysis of Pacific Ocean zooplankton by videomicroscopy and DNA barcoding: Hydrozoa. [PDF]
Most, but not all cnidarian species in the class Hydrozoa have a life cycle in which a colonial, asexually reproducing hydroid phase alternates with a free-swimming, sexually reproducing medusa phase. They are not well known, in part because many of them

Mitochondrial genome comparison reveals the evolution of cnidarians. [PDF]
First of all, we used mt‐genomes as many as possible published before to analyze the evolutionary relationship. Secondly, more recent studies based on mitochondrial whole‐genome sequences have suggested that Anthozoa are polyphyletic, with the subclasses Octocorallia being a sister group with Medusozoa.

Macroscale abundance patterns of hydromedusae in the temperate Southwestern Atlantic (27°-56° S). [PDF]
Gelatinous organisms are crucial components of marine ecosystems and some species imply social and economic consequences. However, certain geographic areas, such as the temperate Southwestern Atlantic (SWA, 27 - 56 S), remain understudied in terms of ...

Epiphytic hydroids (Hydrozoa: Anthoathecata and Leptothecata) of the World [PDF]
Hydroids are an important component of marine epiphytic communities worldwide. We compiled data from several faunistic, taxonomic, and ecologic studies to prepare a list of 200 morphotypes (46 Anthoathecates and 154 Leptothecates) and their respective ...

Check List of Iran marine Cnidarians (Animalia, Cnidaria) [PDF]
There is an urgent need for quality control of marine species data published in domestic journals and open access databases. We extracted 149 accepted Cnidarian species after the quality control process on available published records on the OBIS data ...

Coevolution of the Tlx homeobox gene with medusa development (Cnidaria: Medusozoa). [PDF]
Cnidarians display a wide diversity of life cycles. Among the main cnidarian clades, only Medusozoa possesses a swimming life cycle stage called the medusa, alternating with a benthic polyp stage.
