Spatial Ecology of the Association between Demosponges and Nemalecium lighti at Bonaire, Dutch Caribbean

open access: yesDiversity, 2022
Coral reefs are known to be among the most biodiverse marine ecosystems and one of the richest in terms of associations and species interactions, especially those involving invertebrates such as corals and sponges.

Localization of Multiple Jellyfish Toxins Shows Specificity for Functionally Distinct Polyps and Nematocyst Types in a Colonial Hydrozoan

open access: yesToxins, 2023
Hydractinia symbiolongicarpus is a colonial hydrozoan that displays a division of labor through morphologically distinct and functionally specialized polyp types.

Comparative Analysis of the Soluble Proteome and the Cytolytic Activity of Unbleached and Bleached Millepora complanata (“Fire Coral”) from the Mexican Caribbean

open access: yesMarine Drugs, 2019
Coral bleaching caused by global warming has resulted in massive damage to coral reefs worldwide. Studies addressing the consequences of elevated temperature have focused on organisms of the class Anthozoa, and up to now, there is little information ...

Wind Drifting vs. Pulsating Swimming Jellyfish: Respiratory Metabolism and Composition Differences in Physalis physalis, Velella velella, Aurelia aurita, and Pelagia noctiluca

open access: yesFrontiers in Marine Science, 2022
Physalia physalis and Velella velella, are among the few marine organisms that harness the wind for their locomotion, whereas other cnidarian jellyfish make use of their pulsating bell-shaped bodies to propel themselves through the seas.

Una síntesis de las localidades ibéricas conocidas para Craspedacusta sowerbii Lankester, 1880 (Cnidaria: Hydrozoa): nuevo registro para España procedente de la vega del Guadalquivir

open access: yesGraellsia, 2018
Las especies exóticas invasoras son una de las mayores amenazas para la biodiversidad. Particularmente, las especies de cnidarios son frecuentemente dispersadas lejos de sus áreas de origen por mediación de actividades humanas.

Mitochondrial genome of the freshwater jellyfish Craspedacusta sowerbyi and phylogenetics of Medusozoa.

open access: yesPLoS ONE, 2012
The 17,922 base pairs (bp) nucleotide sequence of the linear mitochondrial DNA (mtDNA) molecule of the freshwater jellyfish Craspedacusta sowerbyi (Hydrozoa, Trachylina, Limnomedusae) has been determined.

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.

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 ...

Trends in the diversity, distribution and life history strategy of Arctic Hydrozoa (Cnidaria).

open access: yesPLoS ONE, 2015
This is the first attempt to compile a comprehensive and updated species list for Hydrozoa in the Arctic, encompassing both hydroid and medusa stages and including Siphonophorae.

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
