In recent years we have seen how jellyfish have become increasingly important in the marine ecosystem. They have been around in the sea for hundreds of millions of years, and are a fundamental part of the marine ecosystem, but their presence is a source of great controversy, as they can affect tourism or fishing. They … Read more
The superabundance of jellyfish does not happen by chance but rather it is a symptom of the fact that the characteristics of the water have changed due to variations in the oceanographic parameters (temperature, salinity). The causes of the existence of great masses of jellyfish are not local, as has been verified by researchers from … Read more
Oceana divers, working in the Cabrera Marine Park to document and record the state of the ecological communities and in surrounding areas, came across large concentrations of jellyfish in the northeastern-facing coves of the archipelago. Thousands of jellyfish of the Pelagia noctiluca species were filmed and photographed by Oceana as they moved within park waters … Read more
It’s summer time, which means that jellyfish are back in the news – recent reports describe thousands clogging beaches in Spain. We thought it might be interesting to look into their reproductive ways and it turns out jellyfish have a rather interesting lifecycle. Interested in learning more? When jellyfish mate, the male’s sperm fertilizes the … Read more

It sounds like the name of a low-budget 80s horror movie, but it’s unfortunately the growing reality in coastal waters around the world. Here’s a quick download on what you need to know about the … Read more
Scientists do not know what could be the reason of increased jellyfish population. The increase of sea water temperature due to climate change, the reduction in the number of predators due to over-fishing and the increase in nutrients due to contamination of the coasts can be some of the reasons. The superabundance of jellyfish does not … Read more
