Reflectance Confocal Microscopy of Skin after the Sting of the Jellyfish Pelagia noctiluca

Case Reports in Dermatology, 2023
Jellyfish are aquatic animals of the phylum Cnidaria found in seas all over the world. They are characterized by the presence of cnidocytes, cells that contain a secretory organelle, the cnidocyst, mainly used for predation and defense purposes. An adult

Three new species of Spongiopsyllus Johnsson, 2000 (Copepoda: Siphonostomatoida: Entomolepididae) associated with Aplysina cauliformis (Carter, 1882) (Porifera: Demospongiae) from Todos-os-Santos Bay, Northeastern Brazil

European Journal of Taxonomy
Entomolepididae is a small siphonostomatoid family with a distinct shield-like body morphology, comprising 9 genera and 20 species. These genera are divided into two subfamilies, mostly based on their body segmentation, the genera with fused pedigerous ...

Description of a new genus of Cryptochiridae (Decapoda: Brachyura) associated with Siderastrea (Anthozoa: Scleractinia), with notes on feeding habits

Scientia Marina, 2012
Members of the Cryptochiridae are small gall-crabs that live as obligate symbionts of scleractinian corals. Only two species have so far been recorded in the western Atlantic Ocean.

Cnidaria

, 2015
AbstractCnidaria are one of the basal groups within the metazoans. They are divided into the Medusozoa (Hydrozoa, Scyphozoa, Staurozoa, and Cubozoa) and the Anthozoa, which are thought to be the basal group within the Cnidaria. Cnidaria together with the Ctenophora are the lowest groups with a nervous system that relies on synaptic conduction and are ...

The complete mitogenome of ghost jellyfish Cyanea nozakii (Cnidaria, Semaeostomeae, Cyaneidae)

Mitochondrial DNA. Part B. Resources, 2018
The cnidarian jellyfishes are impressive organisms to show animal mitochondrial genomic diversities. Their mitogenome structure is linear and tRNA content has one or two in numbers, which is highly different than other metazoans.

A Broad Survey of Gene Body and Repeat Methylation in Cnidaria Reveals a Complex Evolutionary History [PDF]

, 2022
DNA methylation, an important component of eukaryotic epigenetics, varies in pattern and function across Metazoa. Notably, bilaterian vertebrates and invertebrates differ dramatically in gene body methylation (GbM).

Phylogenomics provides a robust topology of the major cnidarian lineages and insights on the origins of key organismal traits

BMC Evolutionary Biology, 2018
Background The phylogeny of Cnidaria has been a source of debate for decades, during which nearly all-possible relationships among the major lineages have been proposed.

Sea Anemones Responding to Sex Hormones, Oxybenzone, and Benzyl Butyl Phthalate: Transcriptional Profiling and in Silico Modelling Provide Clues to Decipher Endocrine Disruption in Cnidarians

Frontiers in Genetics, 2022
Endocrine disruption is suspected in cnidarians, but questions remain how occurs. Steroid sex hormones are detected in corals and sea anemones even though these animals do not have estrogen receptors and their repertoire of steroidogenic enzymes appears ...
