Nerve net differentiation in medusa development of Podocoryne carnea

open access: yesScientia Marina, 2000
The phylum Cnidaria is the most primitive phylum with a well-developed nervous system. Planula larvae and polyps display a diffuse nerve net (plexus), which is densest in the polyp hypostome.

The Histology of Nanomia bijuga (Hydrozoa: Siphonophora) [PDF]

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2014
The siphonophore Nanomia bijuga is a pelagic hydrozoan (Cnidaria) with complex morphological organization. Each siphonophore is made up of many asexually produced, genetically identical zooids that are functionally specialized and morphologically distinct.

Sarsia marii n. sp. (Hydrozoa, Anthomedusae) and the use of 16S rDNA sequences for unpuzzling systematic relationships in Hydrozoa

open access: yesScientia Marina, 2000
A new hydrozoan species, Sarsia marii, is described by using morphological and molecular characters. Both morphological and 16S rDNA data place the new species together with other Sarsia species near the base of a clade that developed, walking tentacles ...

Character Evolution in Hydrozoa (phylum Cnidaria) [PDF]

open access: yesIntegrative and Comparative Biology, 2010
The diversity of hydrozoan life cycles, as manifested in the wide range of polyp, colony, and medusa morphologies, has been appreciated for centuries. Unraveling the complex history of characters involved in this diversity is critical for understanding the processes driving hydrozoan evolution.

Assessing the Efficacy of First-Aid Measures in Physalia sp. Envenomation, Using Solution- and Blood Agarose-Based Models

open access: yesToxins, 2017
Stings from the hydrozoan species in the genus Physalia cause intense, immediate skin pain and elicit serious systemic effects. There has been much scientific debate about the most appropriate first aid for these stings, particularly with regard to ...

The complete mitochondrial genome of the hydrozoan jellyfish Turritopsis lata Lendenfeld, 1885 (Cnidaria; Hydrozoa; Anthoathecata) with molecular phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2021
In this study, we sequenced and analyzed the complete mitochondrial genome (mtgenome) of the hydrozoan jellyfish Turritopsis lata. The mtgenome was a complete linear form (15,047 bp in length, 30.9% A, 42.1% T, 12.5% C, and 14.5% G), including 13 protein

Life history of Perarella schneideri (Hydrozoa, Cytaedidae) in the Ligurian Sea

open access: yesScientia Marina, 2000
Perarella schneideri is a cytaeidid hydroid living in association with the bryozoan Schizoporella longirostris. In this study we have distinguished the presence of two kinds of polyps in its colonies: large gastrozooids and very extensible filiform ...
