Reactive oxygen species (ROS) can damage the lipids, proteins and DNA when produced excessively in cells. Here, we describe the isolation and identification of a novel antioxidant protein named SmP90 from the nematocyst of jellyfish Stomolophus meleagris by 50% ammonium sulfate precipitation and gel filtration chromatography, superdex75.

Journal of Proteomics, 2014
Jellyfish Stomolophus meleagris is a very dangerous animal because of its strong toxicity. However, the composition of the venom is still unclear. Both proteomics and transcriptomics approaches were applied in present study to investigate the major components and their possible relationships to the sting. The proteomics of the venom from S.

Costs of transport for the scyphomedusa Stomolophus meleagris L. Agassiz
Canadian Journal of Zoology, 1987The rhizostome scyphomedusa Stomolophus meleagris swims continuously at speeds up to 15 cm∙s−1. Mean velocities increased as a power function of wet weight up to 70 g but were mostly constant thereafter. Bell pulsations ranged from 1.7 to 3.6 Hz. Reynolds numbers equalled 900 – 13 000. During activity, medusae consumed 0.05 mL O2∙h−1∙g WW−1 (1.2 mL O2∙

Association of the whale shark
This study describes the first record of the whale shark Rhincodon typus association with the cannonball jellyfish Stomolophus meleagris in the Gulf of California, Mexico. Whale sharks were observed swimming and feeding among swarms of jellyfish, suggesting competition and predatory behaviour given the overlap in food preferences between both species ...

The nematocyst proteins of jellyfish Stomolophus meleagris, a complicated mixture, contain many important bioactive molecules. In present study, to gain comprehensive insight into the protein component and search some novel bioactive molecules in the nematocyst proteins, shotgun proteomic analysis of the nematocyst proteins was carried out by nano ...

Toxicology in Vitro, 2013
Jellyfish venom contains various toxins and can cause itching, edema, muscle aches, shortness of breath, blood pressure depression, shock or even death after being stung. Hemolytic protein is one of the most hazardous components in the venom. The present study investigated the hemolytic activity of the nematocyst venom from jellyfish Stomolophus ...

Biochemical Pharmacology, 1976
Abstract Toxin from the jellyfish Stomolophus meleagris was found to stimulate both Na + -K + and mitochondrial Mg 2+ ATPase activities at low toxin concentrations and to inhibit these ATPase activities at higher (> 0·2 mg/ml) concentrations. Using discontinuous membrane partition chromatography the toxin was fractionated into six fractions.

Hydrobiologia, 2018
The digestive capacity of jellyfish has barely been studied because of the complexity of their life stage body-forms and sizes. To assess the digestive capacity in the changes from the benthic polyp-form to the pelagic stage in the cannonball jellyfish Stomolophus meleagris, we used fluorometric and spectrophotometric techniques for measuring the ...

The diet and feeding pattern of scyphomedusa Stomolophus meleagris (Rhizostomeae) was studied, by comparing stomach samples from different developmental stages and environmental zooplankton with the aim to determine diet composition, trophic niche breadth, selectivity and feeding overlap of this edible jellyfish species. Samplings were performed during
