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.

Heat shock proteins in Aurelia (cnidaria, scyphozoa)

Journal of Experimental Zoology, 1984
AbstractHeat shock proteins (hsp) in Aurelia identified by one‐dimensional SDS‐PAGE are of sizes 93,83,70,68,45, and 39 kD, the most rapidly labeled being hsp 70 in all developmental stages. Labeled hsp in the polyp are found mostly in the epidermis; gastrodermal nuclei are also labeled.

Nematocytes’ activation in Pelagia noctiluca (Cnidaria, Scyphozoa) oral arms

Journal of Comparative Physiology A, 2012
Nematocytes' discharge is triggered to perform both defense and predation strategies in cnidarians and occurs under chemico-physical stimulation. In this study, different compounds such as amino acids and proteins (mucin, albumin, poly-L: -lysine, trypsin), sugars and N-acetylate sugars (N-acetyl neuraminic acid, N-acetyl galactosamine, sucrose ...

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

The morphogenesis of ephyra in Coronatae (Cnidaria, Scyphozoa)

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.

Cnidaria: Scyphozoa and Non-Colonial Hydrozoa

2017
This chapter describes the taxonomy of scyphozoa and non-colonial hydrozoa. The Phylum Cnidaria assembles highly diverse primitive invertebrates that carry stinging cells called cnida. The presence of cnida, which are organized in specialized structures called cnidocysts (or nematocysts), makes the organisms of this group venomous to varying degrees ...
