The development of a rowing jellyfish biomimetic robot termed as "Robojelly", has led to the discovery of a passive flexible flap located between the flexion point and bell margin on the Aurelia aurita. A comparative analysis of biomimetic robots showed that the presence of a passive flexible flap results in a significant increase in the swimming performance. In this work we further investigate...

Tarakan city has the potential of marine biological resources that are very abundant such as fish, shrimp, seaweed and even jellyfish. Jellyfish is one aquatic commodities found in almost all waters Indonesia. a source nutrient-rich foods give high economic value. This due to lack information about nutritional content The purpose this study determine proximate fresh dry Rhizostoma Pulmo researc...

On December 10, 2008 Osamu Shimomura, Martin Chalfie and Roger Tsien were awarded the Nobel Prize in Chemistry for "the discovery and development of the green fluorescent protein, GFP". The path taken by this jellyfish protein to become one of the most useful tools in modern science and medicine is described. Osamu Shimomura painstakingly isolated GFP from hundreds of thousands of jellyfish, ch...

We present a 15-year-old female patient with an anaphylactic reaction to a jellyfish sting, sustained while surfing in the Mediterranean Sea. She experienced immediate difficulty in breathing, hoarseness and itching and was taken by ambulance to the emergency department, receiving intramuscular adrenaline on the way. She presented with periorbital swelling and facial edema and improved with sys...

We examined the foraging process in the jellyfish Sarsia tubulosa feeding on three types of prey: cirripede nauplii, cypris larvae, and Acartia tonsa copepodites. Clearance rate was used as measure of prey selectivity. To estimate maximal clearance rate (Fmax), we used a predictive encounter model with input parameters quantified from video observations. Both encounter rate and handling efficie...

The mesogloea collagen of a primitive animal, the jellyfish Stomolophus nomurai, belonging to the class Scyphozoa in the Coelenterata, was studied with respect to its chain structure. Most of the mesogloea collagen was solubilized by limited digestion with pepsin and isolated by selective precipitation at 0.9 M NaCl in 0.5 M acetic acid. Upon denaturation, the pepsinsolubilized collagen produce...

The Northern California Current (NCC) is a seasonally productive and open ecosystem. It is home to both a diverse endemic community and to seasonally transient species. Productivity and food web structure vary seasonally, interannually, and decadally due to variability in coastal upwelling, climate-scale physical processes, and the migratory species entering the system. The composition of the p...

On day 19, vemurafenib therapy was discontinued, and within 7days thereafter, the feverhad improved, and theelectrolyte profile had normalized. Tumor assessment showed a major tumoral response. On day 29, vemurafenib treatment was restarted at half dose, leading within 21 days (day 50) to a relap...

It is well-known to swimmers, divers, and beachgoers that coelenterates such as the Portuguese man-of-war (Physalia physalis), true jellyfish such as the box jellyfish, sea anemone, true coral, and fire coral can inflict painful and sometimes fatal stings. As a result, these organisms are avoided by humans and most sea creatures; however, indirect contact with the skin may occur. For example, c...
