The morphogenesis of ephyra in Coronatae (Cnidaria, Scyphozoa) [PDF]

Marine Biology, 2007
The morphogenesis of ephyrae of Atorella vanhoeffeni Bigelow, 1909 (Werner, 1967) and of Nausithoe maculata Jarms, 1990 during strobilation is described. We found differences in the developmental pattern of marginal structures and structural changes of longitudinal muscle tubes in particular.

The endodermal nerve net of Scyphozoa

Journal of Morphology, 1971
AbstractThe endodermal nerve nets of the scyphozoan jellyfish Phacellophora camtschatica and Cyanea capillata were stained with methylene blue. Small animals (3–7.5 cm in diameter) stained easily. The endodermal nerve net of both species is a synaptic net consisting of bipolar and some few tripolar nerve cells with unbranched neurites.

A checklist of the Medusae (Hydrozoa, Scyphozoa and Cubozoa) of Mexico

Zootaxa, 2003
A list of 169 medusae species in 45 families recorded in Mexican waters is presented for the first time. 86 species (50.8%) were found in the Pacific Ocean, 75 species (44.3%) in the Gulf of Mexico, and 88 (52%) in the Mexican Caribbean Sea. Only 17 species (10%) were common to the three regions.

Integrating molecular and morphological evidence revives the blubber jellyfish, Catostylus purpurus (Scyphozoa: Rhizostomeae; Catostylidae) of the Indo-Pacific (Philippines)

Journal of the Marine Biological Association of the United Kingdom
Jellyfishes have ecological and societal value, but our understanding of taxonomic identity of many jellyfish species remains limited. Here, an approach integrating morphological and molecular (16S ribosomal RNA and cytochrome oxidase I) data enables ...

Cytotoxicity of the venom of Pelagia noctiluca forskål (Cnidaria: Scyphozoa)

Toxicon, 2002
The activity of Pelagia noctiluca venom was never assessed on cultured cells; therefore, we have evaluated on V79 cells the cytotoxicity, genotoxicity and ATP depletion induced after treatment. Venom did not cause alteration on cell DNA, but showed remarkable cytotoxic properties. With the highest nematocyst concentration (150,000 nematocyst/ml) 74 and
