To identify QQ activities of Aurelia aurita-associated microbes, over hundred bacteria were isolated from different life stages of the jellyfish, of which 25% showed QQ activities against AHL as well as AI-2-mediated QS using a recently established reporter system (Weiland-Bräuer et al., 2015...
Even though sharks are the hungry monsters of the sea, they don’t threatenhumans. People are less likely to encounter sharks than other marine animals like jellyfish. Sharks are highly sensitive to disturbances in the water, so they steer clear of swimmers. Even whensharks attack humans, it...

Another type of fossilization, known as carbonization, occurs when soft tissues are preserved as thin films of carbon. Leaves and tissue of soft-bodied organisms such as jellyfish or worms may accumulate, become buried and compressed, and lose their volatile constituents. The carbon often remain...

Jellyfish havea stalked (polyp) phase, when they are attached to coastal reefs, and a jellyfish (medusa) phase, when they float among the plankton. The medusa is the reproductive stage; their eggs are fertilised internally and develop into free-swimming planula larvae. ...
