New online report on massive jellyfish swarms released
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. Areas that are currently particularly hard-hit by these squishy animals include Hawaii, the Gulf of Mexico, the east coast of the US, the Bering Sea, the Mediterranean Sea, Australia, the Black Sea and other European seas, the Sea of Japan, the North Sea and Namibia.

Voracious comb jellyfish 'invisible' to prey
Despite its primitive structure, the North American comb jellyfish can sneak up on its prey like a high-tech stealth submarine, making it a successful predator. Researchers, including one from the University of Gothenburg, have now been able to show how the jellyfish makes itself hydrodynamically (2010-10-10)

Anyone for crispy jellyfish?
The world needs new foods, and we are gradually getting used to the idea of having to eat seaweed and insects. So jellyfish on our plates would not put us off. Right? (2017-07-27)

These jellyfish aren't just drifters
Jellyfish might look like mere drifters, but some of them have a remarkable ability to detect the direction of ocean currents and to swim strongly against them, according to new evidence in free-ranging barrel-jellyfish reported in the Cell Press journal Current Biology on Jan. 22. (2015-01-22)

The life cycle of a jellyfish (and a way to control it)
Those free-swimming jellyfish in the sea don't start out in that familiar medusa form, but rather start as sessile and asexual polyps. Now, researchers reporting in the Cell Press journal Current Biology on January 16 have discovered what triggers that transformation in the moon jellyfish (Aurelia aurita). The key is a novel metamorphosis hormone that accumulates during the cold winter to induce a synchronized emergence of jellyfish in the spring. (2014-01-16)

A research challenges the theories on the global increase in jellyfish population
An international team with CSIC participation asserts that there is no (2012-02-22)

Study reveals jellyfish create a 'virtual wall' to enhance performance
New discovery finds that Jellyfish create a ''ground effect,'' similar to how air squeezes between an airplane and ground during take-off, which builds pressure and a force that boosts performance. Never before has it been proven that an animal can create this phenomenon away from a solid boundary, let alone the open ocean. (2021-01-08)

The eyes have it! How box jellyfish avoid banging into things
Box jellyfish are much more active swimmers than other jellyfish -- they exhibit strong directional swimming, are able to perform rapid 180-degree turns, and can deftly move in between objects. So how do they manage to maneuver the obstacle course that is in the sea bed? Given that they possess an impressive 24 eyes, one would think they would be well-equipped for this challenge! (2007-03-30)

'Jellyfish joyride' a threat to the oceans
New research led by CSIRO Climate Adaptation Flagship and University of Queensland scientist, Dr Anthony Richardson, presents convincing evidence that this (2009-06-09)

DNA tests on albatross poo reveal secret diet of top predator
A study that used DNA tests to analyse the scats of one of the world's most numerous albatrosses has revealed surprising results about the top predator's diet. DNA analysis of 1460 scats from breeding sites around the Southern Ocean has shown that the diet of black-browed albatrosses contains a much higher proportion of jellyfish than previously thought. (2017-10-18)

Baby fish lose poisonous protectors in acidified oceans
A common close partnership which sees baby fish sheltering from predators among the poisonous tentacles of jellyfish will be harmed under predicted ocean acidification, a new University of Adelaide study has found. (2016-06-28)

Jellyfish dominate fish in over-harvested Namibian waters
By sampling sea life in a heavily fished region off the coast of Namibia, researchers have found that jellyfish have actually overtaken fish in terms of the biomass they contribute to this ocean region. The findings represent a careful quantitative analysis of what's been called a (2006-07-10)

Decaying jellyfish blooms can cause temporary changes to water column food webs
Decaying jellyfish blooms fuel the rapid growth of just a few specific strains of seawater bacteria, causing temporary changes to the water column food web. This is the finding of a new study furthering our understanding of how jellyfish blooms, which are happening with increasing frequency, impact marine ecosystems. It details these fast-growing bacteria effectively reduce the amount of jellyfish detrital material reaching the seafloor, keeping it instead within the water column food web. (2020-10-30)

Scientists uncover a centuries-old case of mistaken identity in the Chesapeake Bay
Scientists recently discovered that some jellyfish in the Bay are quite different from their ocean cousins. This led scientists from NOAA and the Smithsonian Institution's National Museum of Natural History to declare them as two different species. (2017-10-13)

What are those big jellyfish fossils doing in Wisconsin?
Jellyfish fossils are rare--not having a skeleton, they easily decay. So why is an entire horde of them preserved in central Wisconsin? Whitey Hagadorn from Caltech wondered the same thing about this exclusive deposit in the Upper Cambrian Mt. Simon-Wonewoc Sandstone in central Wisconsin. During the Cambrian, Wisconsin enjoyed a tropical environment and was covered by a shallow inland sea. In the February GEOLOGY, Hagadorn and colleagues hypothesize how these jellyfish were preserved. (2002-01-24)

What makes a jellyfish?
Genomic study reveals how jellyfish develop into floating beauties, rather than staying stationary like corals or sea anemones. (2019-04-15)

Through unique eyes, box jellyfish look out to the world above the water
Box jellyfish may seem like rather simple creatures, but in fact their visual system is anything but. They've got no fewer than 24 eyes of four different kinds. Now, researchers reporting online on April 28 in Current Biology, a Cell Press publication, have evidence revealing that four of those eyes always peer up out of the water, regardless of the way the rest of the animal is oriented. (2011-04-28)

Marine scientists use JeDI to create world's first global jellyfish database
An international study, led by the University of Southampton, has led to the creation of the world's first global database of jellyfish records to map jellyfish populations in the oceans. (2014-05-15)

Global experts question claims about jellyfish populations
Blooms, or proliferation, of jellyfish have shown a substantial, visible impact on coastal populations -- clogged nets for fishermen, stinging waters for tourists, even choked intake lines for power plants -- and recent media reports have created a perception that the world's oceans are experiencing increases in jellyfish due to human activities such as global warming and overharvesting of fish. (2012-02-01)

Drones as stinger spotters
Researchers from James Cook University in Cairns have demonstrated, for the first time, the potential for off-the-shelf drones to be used to detect deadly box jellyfish. (2020-10-29)

Global experts question claims about jellyfish populations
A global study has questioned claims that jellyfish are increasing worldwide. (2012-02-01)

Ships bring alien jellyfish invaders to our shores
Marine environments around the world are being threatened by exotic species of the moon jellyfish being dispersed by international shipping, according to new research. By simulating the movement of the jellyfish - of the genus Aurelia - over a 7,000 year period the study provides strong evidence that their world-wide dispersal post-dates European global shipping and trade that began almost 500 hundred years ago. (2005-08-15)

New discovery: Common jellyfish is actually two species
UD professor and alum discover sea nettle jellyfish found in Rehoboth and Chesapeake Bay is actually two species. (2017-11-21)

How moon jellyfish get about
With their translucent bells, moon jellyfish (Aurelia aurita) move around the oceans in a very efficient way. Scientists at the University of Bonn have now used a mathematical model to investigate how these cnidarians manage to use their neural networks to control their locomotion even when they are injured. The results may also contribute to the optimization of underwater robots. The study has already been published online in the journal eLife. (2020-01-23)

Scientists discover stinging truths about jellyfish blooms in the Bering Sea
A new study helps explain a cyclic increase and decrease of jellyfish populations, which transformed parts of the Bering Sea -- one of the United States' most productive fisheries -- into veritable jellytoriums during the 1990s. (2008-05-29)

Jellyfish's 'superpowers' gained through cellular mechanism
Jellyfish are animals that possess the unique ability to regenerate body parts. A team of Japanese scientists has now revealed the cellular mechanisms that give jellyfish these remarkable 'superpowers.' (2019-10-01)

Wound healing or regeneration -- the environment decides?
For humans, the loss of limbs is almost always an irreversible catastrophe. Many animals, however, are not only able to heal wounds but even to replace whole body parts. Biologists from the GEOMAR Helmholtz Centre for Ocean Research Kiel have now been able to prove for the first time that comb jellyfish can switch between two completely different self-healing processes depending on the environmental conditions. The study has been published in the international journal Scientific Reports. (2017-11-29)

The surprising, ancient behavior of jellyfish
The discovery that primitive jellyfish sleep suggests that sleep is an ancient, evolutionarily conserved behavior. (2017-09-21)

Fossil orphans reunited with their parents after half a billion years
Everyone wants to be with their family for Christmas, but spare a thought for a group of orphan fossils that have been separated from their parents since the dawn of animal evolution, over half a billion years ago. (2017-12-12)

Popular science helps to discover the abundance of this jellyfish
When the Rhizostoma luteum jellyfish was discovered at the beginning of the 19th century in the waters of the Strait of Gibraltar, only nine specimens were identified. For years, it was so inconspicuous that later, in the 20th century, it failed to turn up for six decades. A team of scientists, with the help of a citizen initiative, has now confirmed that it is not really as difficult to find as previously believed. (2018-11-13)

New research findings to standardise first aid treatment of jellyfish stings
New research from NUI Galway and the University of Hawaii at Manoa has identified the best way to treat a sting from the lions mane jellyfish (Cyanea capillata). (2017-07-27)

Jellyfish Help To Make Sugar Smarter
A gene that causes jellyfish to glow in the dark is being used by Australian scientists as a marker gene in experiments to improve the quality of sugar and other crops. (1998-05-04)

Searching for the origin of muscles
Ulrich Technau from the University of Vienna has addressed the origin of musculature. His analysis reveals for the first time that some central components of muscles of higher animals are much older than previously assumed. These results, now published in the renowned journal Nature, indicate that muscle-like cell contraction originated already very early during animal evolution, while the specialization of basal muscle cell types, such as striated muscles, occurred only later and several times independently. (2012-06-28)

Should you pee on a jellyfish sting? (video)
We all know the evils that come from a run-in with a jellyfish's tentacles. But thankfully, we can resort to peeing on a sting to make the pain go away -- or can we? Filmed at San Francisco's Aquarium of the Bay, the latest Reactions episode explains the fearsome chemistry of jellyfish stings, and debunks this age-old beach myth: https://youtu.be/KDj2t4-bn1g. (2017-05-23)

Jellyfish blooms shunt food energy from fish to bacteria
Study by researchers at the Virginia Institute of Marine Science shows that jellyfish can drastically alter marine food webs by shunting food energy from fish toward bacteria. (2011-06-06)

Fossil record reveals elusive jellyfish more than 500 million years old
Using recently discovered 'fossil snapshots' found in rocks more than 500 million years old, three University of Kansas researchers have described the oldest definitive jellyfish ever found. In a paper published in PLoS ONE on Oct. 31, the researchers describe four types of cnidarian fossils preserving traits that allow them to be related to modern orders and families of jellyfish. The specimens are about 200 million years older than the oldest previously discovered jellyfish fossils. (2007-10-30)
