Under the sea ice, behold the ancient Arctic jellyfish

The doings of creatures under the Arctic sea ice are many, but they are rarely observed by humans; it's pretty hard to get under the ice to look. In recent years, marine biologist Andy Juhl and his colleagues have gotten ...

Predicting jellyfish 'invasions' at coastal power stations

Scientists at the University of Bristol are working with the energy industry to develop an 'early warning tool' to predict the sudden, en masse appearance of jellyfish swarms which can cause serious problems by clogging the ...

Populated Puget Sound sees stark shifts in marine fish species

The most populated areas of Puget Sound have experienced striking shifts in marine species, with declines in herring and smelt that have long provided food for other marine life and big increases in the catch of jellyfish, ...

Distinctive body type aids long life and predation

Jellyfish (Cnidarian medusa) have unique body plans that violate a universal law of biology and facilitate their longevity and their propensity to form blooms, according to an international study involving UWA scientists.

Unraveling jellyfish metamorphosis

How does one genome create two completely different body plans in one animal? This was the question Konstantin Khalturin was attempting to answer when he began working on jellyfish. The fascinating story he discovered along ...

'Trojan horse' effect may explain jellyfish blooms

(Phys.org)—Man-made structures such as harbours, tourist facilities, oil rigs and aquaculture farms provide ideal sanctuaries for jellyfish polyps to flourish and may explain an apparent increase in jellyfish blooms in ...

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 ...

Ridding waters of plastic waste with jellyfish filters

What do microplastic filters, fertilisers and fish feed have in common? They can all be produced using jellyfish. At least, that's what one research team has set out to prove as they look into reducing the plastic waste in ...

Turning jellyfish from a nuisance to useful product

Global climate change and the human impact on marine ecosystems have led to dramatic decreases in the number of fish in the ocean. It has also had an unforseen side effect: because overfishing decreases the numbers of jellyfish ...
