For #WorldJellyfishDay it’s a smack of jellyfish!
The collective noun for a group of jellyfish is a “smack”. This amuses me, because I imagine them smacking their tentacles together in some sort of deepsea high five. To be honest, marine biologists speak of ‘blooms’ and we do tend to lump in a bunch of soft-bodies marine creatures into the term jellyfish, all of the gelatinous zooplankton in fact.... but ‘a smack of jellyfish’ is 🧵

#Jellyfish attack #NuclearPowerPlant. Again.
By Susan D’Agostino | October 28, 2021
" #Scotland’s only working nuclear power plant at #Torness shut down in an emergency procedure when jellyfish clogged the sea water-cooling intake pipes at the plant, according to the Scotland Herald this week. Without access to cool water, a nuclear power plant risks overheating. The intake pipes can also be damaged, which disrupts power generation. And ocean life that gets sucked into a power plant’s intake pipes risks death.
[...]
"The clash between gelatinous jellyfish and hulking nuclear power plants has a long history. These spineless, brainless, bloodless creatures shut down the Torness nuclear power plant in 2011 at a cost of approximately $1.5 million per day, according to one estimate. Swarms of these invertebrates have also been responsible for nuclear power plant shutdowns in Israel, Japan, the United States, the #Philippines, #SouthKorea, and Sweden.
"Humans have unwittingly nurtured the adversarial relationship between jellyfish and nuclear power plants. That is, human-induced #ClimateChange has raised ocean water temperatures, setting conditions for larger-than-usual jellyfish populations. Further, the relatively warm water near nuclear power plant discharge outlets may attract jellyfish swarms, according to one study. Also, #pollution has lowered #oxygen levels in sea water, which jellyfish tolerate more than other marine animals, leading to their proliferation.
"Some look at jellyfish and see elegant ballerinas of the sea, while others view them as pests. Either way, they are nothing if not resilient. Jellyfish are 95 percent water, drift in topical waters and the Arctic Ocean, and thrive in the ocean’s bottom as well as on its surface. Nuclear power plant operators might take note: Older-than-dinosaur jellyfish are likely here to stay."

#Jellyfish Keep Attacking #NuclearPowerPlants
By Gabriel Geiger
November 2, 2021"Jellyfish are continuing to clog the cooling intake pipes of a nuclear power plant in Scotland, which has previously prompted a temporary shutdowns of the plant.
"The #TornessNuclearPowerPlant has reported concerns regarding jellyfish as far back as 2011, when it was forced to shut down for nearly a week—at an estimated cost of $1.5 million a day—because of the free-swimming marine animals.
"In a short comment to Motherboard, #EDFEnergy, which runs the Torness plant, said that 'jellyfish blooms are an occasional issue for our power stations,' but also said that media reports claiming the plant had recently been taken offline because of jellyfish are 'inaccurate.' '[There were] no emergency procedures this or last week related to jellyfish or otherwise,' a spokesperson said. [Um, did they previously work for #TEPCOLies?]
" 'Like many other seaside power plants, the Torness plant uses seawater to prevent overheating. While there are measures in place to prevent aquatic life from entering the intake pipes, according to the #BulletinOfTheAtomicScientists, they are no match for the sheer number of jellyfish that come during so-called 'jellyfish blooms.'
" 'Usually, screens prevent aquatic life and similar debris from being drawn into the power plants’ cooling system,' the Bulletin of the Atomic Scientists wrote in a 2015 blog post. 'But when sufficiently large volumes of jellyfish or other aquatic life are pulled in, they block the screens, reducing the volume of water coming in and forcing the reactor to shut down.'
"While the case in Scotland has once again spotlighted concerns regarding the jellyfish and potential power plant shutdowns, these concerns are far from new. In 2008, a swarm of jellyfish shut down a nuclear power plant [#DiabloCanyon -- which had another incident in 2024] in #California, and three years later the same occurred at a plant in Japan [#Shimane]. In 2017, jellyfish clogged a power plant in Israel [#Hadera]."

#Jellyfish are taking over the world – and #ClimateChange could be to blame
Jan 8, 2019
by Sean Fleming
Senior Writer, Forum Stories"For 500 million years, jellyfish have been part of the maritime #ecosystem, but now they’re poised to take over the earth.
"They have no brain, no eyes, no spine, not even blood, but they have a remarkable capacity to reproduce and can pack an impressive sting, both literally and figuratively.
"Most recently, vast numbers of bluebottle jellyfish were pushed ashore by unusually strong winds and spells of hot weather in #QueenslandAustralia, stinging thousands of people and forcing the closure of popular swimming spots. About 13,000 stings were recorded in the past week.
"In June last year, over the course of just one week, over 1,000 people were stung in Volusia County, #Florida, following a period of exceptionally prolific jellyfish blooms. The explosion in their numbers has been attributed to warming seas and even increased pollution; unlike many other marine creatures, jellyfish can cope with reduced oxygen levels.
Small but deadly – at least some of the time
"Typically, jellyfish range in size from 1cm to 40cm. But they can be significantly larger – the #LionsManeJellyfish, for example, can reach 1.8 metres wide, with tentacles over 15 metres long.
"For the most part, the sting of a jellyfish is more unpleasant than it is harmful. The pain comes from venom delivered via millions of microscopic barbs in the creatures’ tentacles. Most jellyfish stings will only have a localized effect on the victim – redness, swelling, and discomfort where the barbs make contact with the skin.
"Some, however, will prompt a systemic, whole body, reaction. These may take several hours to emerge and can include symptoms such as headaches, nausea and drowsiness.
"In rare cases, the sting can be fatal. This is true of the #BoxJellyfish, which is spreading into waters that had previously been too cool to support it; its venom causes a severe reaction that can cause death within minutes.
A force of destruction
"But these booming jellyfish populations are doing far more harm than ruining people’s trips to the beach. In fact, the scope of their disruption has extended far beyond the water’s edge.
"In 2011, both reactors at the #TornessNuclearPowerPlant in #Scotland were shut down after an invasion of jellyfish started blocking the cooling filters. Two years later, the jellyfish struck again – this time in #Sweden. They forced the closure of the #OskarshamnNuclearPowerPlant, which contains the world’s largest boiling-water reactor.
"The island of Luzon, home of the Phillippines’ capital Manilla, suffered a blackout in 1999 due to jellyfish, and in 2006 the #USSRonaldReagan, a nuclear-powered aircraft carrier, was brought to a standstill by thousands of the little creatures. And while these events may stand out as exceptions, they are increasing in both scale and frequency.
"From sea-bed diamond mining in Namibia to salmon farming in Ireland, even jeopardising the sustainability of beluga caviar farming in the Caspian Sea, jellyfish are as destructive as they are abundant. And that abundance is being caused by a variety of factors, many of which are related to human activity.
Some like it hot
"Over the last hundred or so years, the average surface temperature of the world’s seas has risen by about 0.9°C. As the oceans get warmer, marine animals are able to spread into areas that had historically been too cold. Oxygen levels in the sea have fallen by around 2% over the last 50 years, due to rising temperatures and #pollution [including #NuclearOceanDumping, which reduces oxygen levels]
"Jellyfish can thrive in areas with lower oxygen levels, where other animals suffer. But there are other factors at work, too. Fishing has depleted the global stocks of some of the jellyfish’s natural predators – such as #tuna and #swordfish – and some they compete with for food – such as anchovies. With more food and fewer predators, some jellyfish populations can grow unchecked.
"In the #BlackSea, unchecked population growth is precisely what’s happened. #AnchovyFishing in the region had caused harm to the Black Sea’s ecosystem by the time stowaway jellyfish made the journey there from the eastern seaboard of the USA. Most likely transported in the ballast water of ships that made the crossing, 1982 saw the arrival of the warty comb jelly. By 1990, there were 900 million tons of them in the Black Sea.
"There are believed to be around 200 different species of jellyfish, not all of which can sting, and some are considered edible. This could offer one potential, and creative, approach toward dealing with an over-abundance of jellyfish – co-opting them onto our dinner plates." [That's one way to deal with invasive species -- eat them into extinction!]

Exploring the Diverse Underwater World of Mozambique
During a two-week diving adventure off the coast of Tofo Beach in Mozambique, I immersed myself in its vibrant underwater world almost every day. Over the course of about 22 dives, each descent revealed something new— from tiny reef dwellers to larger pelagic visitors. The marine biodiversity of Tofo Beach makes every dive feel distinct, offering moments that stay with you long after surfacing.

Here’s a clip of a diver observing the graceful movements of a jellyfish off the coast of Tofo Beach. These translucent drifters pulse gently through the water, their tentacles trailing like ribbons of light. Watching them up close is mesmerizing—an intimate glimpse into the fragile beauty and balance of ocean life.

All the other #Jellyfish laughed when Leopold started researching the #Armadillo for a personal project. But now that tourist season was peaking, he was the only one who could safely navigate the bay.
Alle anderen #Qualle lachten, als Leopold anfing, das #Gürteltier für ein persönliches Projekt zu recherchieren. Aber jetzt, da die Touristensaison ihren Höhepunkt erreichte, war er der einzige, der sicher durch die Bucht navigieren konnte.
