Two swimming modes in Trachymedusae; bell kinematics and the role of giant axons. [PDF]
J Exp Biol, 2021 Although members of the Rhopalonematidae family (Cnidaria, Hydrozoa, Trachymedusae) are known to exhibit unusually powerful jet swimming in addition to their more normal slow swimming behaviour, for the most part, reports are rare and anecdotal.

Environmental DNA surveys detect distinct metazoan communities across abyssal plains and seamounts in the western Clarion Clipperton Zone. [PDF]
Mol Ecol, 2020 Abstract The deep seafloor serves as a reservoir of biodiversity in the global ocean, with >80% of invertebrates at abyssal depths still undescribed. These diverse and remote deep‐sea communities are critically under‐sampled and increasingly threatened by anthropogenic impacts, including future polymetallic nodule mining.

Diversity and life-cycle analysis of Pacific Ocean zooplankton by videomicroscopy and DNA barcoding: Hydrozoa. [PDF]
PLoS ONE, 2019 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

Scientia Marina, 2000 Although systematic treatments of Hydrozoa have been notoriously difficult, a great deal of useful information on morphologies and life histories has steadily accumulated. From the assimilation of this information, numerous hypotheses of the phylogenetic

Hidden gems: Scattered knowledge hampered freshwater jellyfish research over the past one-and-a-half centuries. [PDF]
Ecol EvolApproximately 150 years of research on freshwater jellyfish globally have resulted in a considerable amount of information. However, this is not comprehensively available to most researchers worldwide. Scattered information allows only for a fragmented view of the research field, which mediated by climate change received increasing importance.

Check List of Iran marine Cnidarians (Animalia, Cnidaria) [PDF]
Iranian Journal of Animal Biosystematics, 2020 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 ...

Limnology and Oceanography, Volume 68, Issue 12, Page 2688-2702, December 2023., 2023 Abstract The effects of environmental change on zooplankton communities, and more broadly, pelagic ecosystems are difficult to predict due to the high diversity of ecological strategies and complex interspecific interactions within the zooplankton. Trait‐based approaches can define zooplankton functional groups with distinct responses to environmental ...

Integrating siphonophores into marine food‐web ecology
Limnology and Oceanography Letters, Volume 7, Issue 2, Page 81-95, April 2022., 2022 Abstract Siphonophores are a clade of understudied colonial hydrozoans (Cnidaria) that are abundant predators in oceanic ecosystems, with species present across the water column. We (1) synthesize current knowledge about siphonophore trophic ecology and predator–prey interactions, (2) analyze siphonophore‐prey networks to compare food‐web topology ...
