A new study helps explain a cyclic increase and decrease of jellyfish populations, which transformed parts of the Bering Sea--one of the U.S.'s most productive fisheries--into veritable jellytoriums during the 1990s. The study shows that the availability of food for jellyfish may cap the potential size of the Bering Sea's jellyfish population, even while other factors, such as rising temperatures, may encourage its continued growth. These results indicate that "anticipated temperature...

By Ehrenberg, Rachel Studies of medusan motion reveal secrets of the Earth's first muscle-powered swimmers From the Jetsons to James Bond, flying via jet pack has become an icon of the futuristic way to travel. But jet propulsion is actually older than the Flintstones. It's a standard means of locomotion for jellyfish, the earliest animals to swim the seas using muscles. Jellies have been jet-propelling for at least 550 million years, yet only recently have scientists begun to understand...

Invasive Australian jellyfish could pose a threat to the U.S. commercial fishing and shrimping industry. The exotic jellyfish, Phyllorhiza punctata, were first spotted in the Gulf of Mexico in 2000. They've moved east since then and are now being reported in waters from southwestern Louisiana to Morehead City, N.C. Researchers said the jellyfish present little to no danger to humans in terms of their sting, but they could hurt fishermen and shrimpers by fouling trawling nets and eating...

Giant jellyfish have been spotted in large numbers in the usually chilly waters surrounding Norway, an Oslo University scientist reported. Hege Vestheim told the Tonsbergs Blad newspaper that she photographed large numbers of the giant comb jellyfish in Norwegian waters last fall. The comb jellyfish, while not dangerous to humans, eats small newly hatched fish and can devastate marine fisheries by disrupting food chains. They were drifting on the surface everywhere, Vestheim told...

MADRID -- Sweltering temperatures sweeping Europe have brought a plague of jellyfish to Spain's eastern seashores, forcing holidaymakers to stay out of the sea, the Red Cross said on Thursday. The unwelcome visitors, which can reach the size of a dinner plate, have flourished thanks to a glut of plankton brought on by higher sea temperatures and a decline in natural predators like dolphins and turtles. The Red Cross has treated more than 10,000 jellyfish stings this summer so far in the...

By Isabel Reynolds TOKYO -- A slimy jellyfish weighing as much as a sumo wrestler has Japan's fishing industry in the grip of its poisonous tentacles. Vast numbers of Echizen kurage, or Nomura's jellyfish, have appeared around Japan's coast since July, clogging and ripping fishing nets and forcing fishermen to spend hours hacking them apart before bringing home their reduced catches. Representatives of fishing communities around the country gathered in Tokyo on Thursday, hoping to thrash out...

MADRID (Reuters) - Unusually high concentrations of jellyfish have appeared along Spain's Mediterranean coast this summer, to the discomfort of thousands of tourists, officials said on Wednesday. The Red Cross said its lifeguards had treated almost 11,000 people for stings on beaches so far this season in the northeastern region of Catalonia alone, twice the number from the same period last year, when the jellyfish count had already begun to rise. Almunecar on the south coast had to cancel...

Fungia scruposa is a species of mushroom coral that lives a single individual rather than as a colony. It starts out life as a small disk attached to dead coral or rock, but by the time it reaches about 1 inch in diameter, it becomes detached. The adult has a single polyp that reaches up to 10 inches in diameter. This is the first species of coral that has been observed eating jellyfish. While most of its diet consists of bacteria and mesozooplankton, it does take larger marine life,...

The White-spotted jellyfish is also known as the Australian spotted jellyfish (Phyllorhiza punctata). The jellyfish feeds primarily on assorted snail species and thrives in the southwestern Pacific. The bell of the White-spotted jellyfish averages 17-19 inches in diameter but there had been a maximum reported size of 24 inches. However, on Sunset Beach in North Carolina in October, 2007, a White-spotted jellyfish was found on the shore measuring in at 28 inches, perhaps the largest to...

The Lion's Mane jellyfish (Cyanea capillata) is native to the northern regions of the Arctic, Atlantic and the Pacific Oceans; there are very few Lion's Mane jellyfish that can be found farther south than 42 degrees north latitude. The Lion's Mane jellyfish is the largest and longest jellyfish known and one of the longest animals in general. In 1870, a Lion's Mane jellyfish was found washed up on the Massachusetts Bay. The bell (body) of the jellyfish had a diameter of 7 feet and 6 inches...
