Massive swarms of stinging jellyfish and jellyfish-like animals are transforming many world-class fisheries and tourist destinations into veritable ‘jellytoriums’ that are intermittently jammed with pulsating, gelatinous creatures, reports the National Science Foundation. Areas that are currently particularly hard-hit by jellyfish include Hawaii, the Gulf of Mexico, the east coast of the U. S., the Bering Sea, the Mediterranean Sea, Australia, the Black Sea and other European seas, the Sea of Japan, the North Sea and Namibia.

A recently released multi-media online report by the National Science Foundation (NSF) – Jellyfish Gone Wild: Environmental Change and Jellyfish Swarms – explains about the changes that are taking place in the world’s jellyfish populations. Jellyfish Gone Wild features incredible photos and videos of giant jellyfish, statistics about jellyfish swarms and explanations about why jellyfish swarms form.

From large swarms of potentially deadly, peanut-sized jellyfish in Australia to swarms of hundreds of millions of refrigerator-sized jellyfish in the Sea of Japan, suspicion is growing that population explosions of jellyfish are being generated by human activities, reports the NSF. Human activities that may contribute to jellyfish swarms include pollution, climate change, introduction of non-native species, overfishing and the presence of artificial structures, such as oil and gas rigs.
