Five jellyfish species you may encounter more often in UK’s warming seas

UK is home to a diverse range of jellyfish species – encounters with them may become more frequent as the ocean warms.

Published

on

While scuba diving off the south-west coast of England this summer, I was lucky to encounter several different species of jellyfish in just a matter of weeks. Many of these, including the compass jellyfish (Chrysaora hysoscella), are already common to UK waters. But among them was one that I had never laid eyes on before – the crystal jelly (Aequorea victoria) – a creature capable of glowing in the dark.

The good news for fellow jellyfish enthusiasts is that both the abundance and diversity of jellyfish around the UK may be on the rise. Warmer sea temperatures mean that jellyfish can now inhabit a wider range of habitats, with some species moving polewards into waters that were once too cold for them.

Research carried out by the Marine Conservation Society (a UK conservation charity) suggests that there is a growing trend in sightings of certain species along the UK’s coastlines. Crystal jellies made up just 1% of UK jellyfish sightings in 2021. By 2022, this had risen to 3%.

Meanwhile, there is evidence suggesting that jellyfish blooms (where the jellyfish population rises suddenly) are increasing in certain regions worldwide, including the UK. This phenomenon is potentially connected to the effects of climate change.

As the waters surrounding the UK continue to warm, it’s possible that people will have even more of an opportunity to watch and admire these diverse and strange animals.

Jellyfish often have an unfairly negative reputation. While it’s true that some jellyfish sting, they never intentionally harm humans. In fact, jellyfish can’t even swim – they are part of the plankton: a group of mostly tiny animals and algae that drift through the sea on currents.

If we observe jellyfish from a safe distance, as we do with other potentially harmful animals, we can admire their intricate body shapes and their rhythmic movement at no risk whatsoever. So, here are five common jellyfish species that people may well see more of as the seas around the UK continue to warm.

1. Compass jellyfish

Compass jellyfish are easy to identify by the dark stripes on their pale bells. These jellyfish can grow to 30cm in diameter, boast long tentacles and are a favourite food for turtles.

This species is often the most commonly reported jellyfish in UK waters. In 2022, almost one-quarter of the UK jellyfish sightings that were reported to the Marine Conservation Society were compass jellies. Compass jellyfish have a very painful sting.

2. Moon jellyfish

Moon jellies (Aurita aurita) have a distinctive appearance. They have relatively short tentacles and are transparent with four purple rings on the top of their bells. They can grow to 40cm in diameter.

These jellyfish can be found almost anywhere in the world, but they are most commonly encountered in coastal waters. Moon jellies have only a mild sting that most people don’t react to.

3. Barrel jellyfish

Barrel jellyfish (Rhizostoma pulmo) are huge compared to most of the other jellyfish species found in the UK. They can grow to up to 1 metre in diameter and have earned the nickname “dustbin lid” jellies due to their size.

Their bell is thick and can be light pink, blue or yellow, but it is usually rimmed with dark purple. Instead of tentacles, barrel jellies have long frilly arms.

Barrel jellies have a relatively mild sting and are even eaten in some parts of the world, including Asia.

4. Lion’s mane jellyfish

Lion’s mane jellyfish (Cyanea capillata) are usually around 50cm in diameter, though they can grow to around 2 metres. These jellies are reddish brown in colour and have both thin tentacles and thick frilly arms.

Due to their size, only young lion’s mane jellies are eaten by fish and turtles. Lion’s mane jellyfish have a painful sting.

5. Mauve stinger

Mauve stingers (Pelagica noctiluca) are small – less than 10cm in diameter – and a beautiful pink or mauve colour. They glow in the dark and can form aggregations, known as a “smack”, that are so large they can clog fishing nets.

Not only do their tentacles sting; their bells can also sting too, which is uncommon among jellyfish.

The UK is fortunate to have such a diversity of jellyfish, only some of which pose any sort of threat to humans. Water-lovers can peacefully enjoy swimming and diving in the sea around the UK if they keep an eye out for jellies and try to avoid touching them – as we should do with all wildlife. Wearing a wetsuit when swimming will also help to prevent stings.

If you do get stung by a jellyfish, rinse the sting in seawater (not freshwater), scrape off any spines and soak in hot water or with hot cloths for at least 30 minutes.

The Marine Conservation Society provides an excellent guide to identifying common UK jellyfish. If you do see a jellyfish in UK waters, whether it’s one of the species above or a more uncommon one, please report your sighting. Jellyfish are hard to catch and count, so this data will improve our understanding of the impact climate change has on UK biodiversity.

The next time you see a jellyfish, don’t be afraid. Instead, take a moment to appreciate its strange, soft beauty.

Health Officials: Man Dies From Bubonic Plague In New Mexico

Authored by Jack Phillips via The Epoch Times (emphasis ours),

Officials in New Mexico confirmed that a resident died from the plague in the United States’ first fatal case in several years.

The New Mexico Department of Health, in a statement, said that a man in Lincoln County “succumbed to the plague.” The man, who was not identified, was hospitalized before his death, officials said.

They further noted that it is the first human case of plague in New Mexico since 2021 and also the first death since 2020, according to the statement. No other details were provided, including how the disease spread to the man.

The agency is now doing outreach in Lincoln County, while “an environmental assessment will also be conducted in the community to look for ongoing risk,” the statement continued.

This tragic incident serves as a clear reminder of the threat posed by this ancient disease and emphasizes the need for heightened community awareness and proactive measures to prevent its spread,” the agency said.

A bacterial disease that spreads via rodents, it is generally spread to people through the bites of infected fleas. The plague, known as the black death or the bubonic plague, can spread by contact with infected animals such as rodents, pets, or wildlife.

The New Mexico Health Department statement said that pets such as dogs and cats that roam and hunt can bring infected fleas back into homes and put residents at risk.

Officials warned people in the area to “avoid sick or dead rodents and rabbits, and their nests and burrows” and to “prevent pets from roaming and hunting.”

“Talk to your veterinarian about using an appropriate flea control product on your pets as not all products are safe for cats, dogs or your children” and “have sick pets examined promptly by a veterinarian,” it added.

“See your doctor about any unexplained illness involving a sudden and severe fever, the statement continued, adding that locals should clean areas around their home that could house rodents like wood piles, junk piles, old vehicles, and brush piles.

The plague, which is spread by the bacteria Yersinia pestis, famously caused the deaths of an estimated hundreds of millions of Europeans in the 14th and 15th centuries following the Mongol invasions. In that pandemic, the bacteria spread via fleas on black rats, which historians say was not known by the people at the time.

Other outbreaks of the plague, such as the Plague of Justinian in the 6th century, are also believed to have killed about one-fifth of the population of the Byzantine Empire, according to historical records and accounts. In 2013, researchers said the Justinian plague was also caused by the Yersinia pestis bacteria.

But in the United States, it is considered a rare disease and usually occurs only in several countries worldwide. Generally, according to the Mayo Clinic, the bacteria affects only a few people in U.S. rural areas in Western states.

Recent cases have occurred mainly in Africa, Asia, and Latin America. Countries with frequent plague cases include Madagascar, the Democratic Republic of Congo, and Peru, the clinic says. There were multiple cases of plague reported in Inner Mongolia, China, in recent years, too.

Symptoms

Symptoms of a bubonic plague infection include headache, chills, fever, and weakness. Health officials say it can usually cause a painful swelling of lymph nodes in the groin, armpit, or neck areas. The swelling usually occurs within about two to eight days.

The disease can generally be treated with antibiotics, but it is usually deadly when not treated, the Mayo Clinic website says.

“Plague is considered a potential bioweapon. The U.S. government has plans and treatments in place if the disease is used as a weapon,” the website also says.

According to data from the U.S. Centers for Disease Control and Prevention, the last time that plague deaths were reported in the United States was in 2020 when two people died.

Riley Gaines Explains How Women's Sports Are Rigged To Promote The Trans Agenda

Is there a light forming when it comes to the long, dark and bewildering tunnel of social justice cultism?  Global events have been so frenetic that many people might not remember, but only a couple years ago Big Tech companies and numerous governments were openly aligned in favor of mass censorship.  Not just to prevent the public from investigating the facts surrounding the pandemic farce, but to silence anyone questioning the validity of woke concepts like trans ideology. 

From 2020-2022 was the closest the west has come in a long time to a complete erasure of freedom of speech.  Even today there are still countries and Europe and places like Canada or Australia that are charging forward with draconian speech laws.  The phrase "radical speech" is starting to circulate within pro-censorship circles in reference to any platform where people are allowed to talk critically.  What is radical speech?  Basically, it's any discussion that runs contrary to the beliefs of the political left.

Open hatred of moderate or conservative ideals is perfectly acceptable, but don't ever shine a negative light on woke activism, or you might be a terrorist.

Riley Gaines has experienced this double standard first hand.  She was even assaulted and taken hostage at an event in 2023 at San Francisco State University when leftists protester tried to trap her in a room and demanded she "pay them to let her go."  Campus police allegedly witnessed the incident but charges were never filed and surveillance footage from the college was never released.  

It's probably the last thing a champion female swimmer ever expects, but her head-on collision with the trans movement and the institutional conspiracy to push it on the public forced her to become a counter-culture voice of reason rather than just an athlete.

For years the independent media argued that no matter how much we expose the insanity of men posing as women to compete and dominate women's sports, nothing will really change until the real female athletes speak up and fight back.  Riley Gaines and those like her represent that necessary rebellion and a desperately needed return to common sense and reason.

In a recent interview on the Joe Rogan Podcast, Gaines related some interesting information on the inner workings of the NCAA and the subversive schemes surrounding trans athletes.  Not only were women participants essentially strong-armed by colleges and officials into quietly going along with the program, there was also a concerted propaganda effort.  Competition ceremonies were rigged as vehicles for promoting trans athletes over everyone else. 

The bottom line?  The competitions didn't matter.  The real women and their achievements didn't matter.  The only thing that mattered to officials were the photo ops; dudes pretending to be chicks posing with awards for the gushing corporate media.  The agenda took precedence.

Lia Thomas, formerly known as William Thomas, was more than an activist invading female sports, he was also apparently a science project fostered and protected by the athletic establishment.  It's important to understand that the political left does not care about female athletes.  They do not care about women's sports.  They don't care about the integrity of the environments they co-opt.  Their only goal is to identify viable platforms with social impact and take control of them.  Women's sports are seen as a vehicle for public indoctrination, nothing more.

The reasons why they covet women's sports are varied, but a primary motive is the desire to assert the fallacy that men and women are "the same" psychologically as well as physically.  They want the deconstruction of biological sex and identity as nothing more than "social constructs" subject to personal preference.  If they can destroy what it means to be a man or a woman, they can destroy the very foundations of relationships, families and even procreation.  

For now it seems as though the trans agenda is hitting a wall with much of the public aware of it and less afraid to criticize it.  Social media companies might be able to silence some people, but they can't silence everyone.  However, there is still a significant threat as the movement continues to target children through the public education system and women's sports are not out of the woods yet.   

The ultimate solution is for women athletes around the world to organize and widely refuse to participate in any competitions in which biological men are allowed.  The only way to save women's sports is for women to be willing to end them, at least until institutions that put doctrine ahead of logic are made irrelevant.

Congress’ failure so far to deliver on promise of tens of billions in new research spending threatens America’s long-term economic competitiveness

A deal that avoided a shutdown also slashed spending for the National Science Foundation, putting it billions below a congressional target intended to…

Federal spending on fundamental scientific research is pivotal to America’s long-term economic competitiveness and growth. But less than two years after agreeing the U.S. needed to invest tens of billions of dollars more in basic research than it had been, Congress is already seriously scaling back its plans.

A package of funding bills recently passed by Congress and signed by President Joe Biden on March 9, 2024, cuts the current fiscal year budget for the National Science Foundation, America’s premier basic science research agency, by over 8% relative to last year. That puts the NSF’s current allocation US$6.6 billion below targets Congress set in 2022.

And the president’s budget blueprint for the next fiscal year, released on March 11, doesn’t look much better. Even assuming his request for the NSF is fully funded, it would still, based on my calculations, leave the agency a total of $15 billion behind the plan Congress laid out to help the U.S. keep up with countries such as China that are rapidly increasing their science budgets.

I am a sociologist who studies how research universities contribute to the public good. I’m also the executive director of the Institute for Research on Innovation and Science, a national university consortium whose members share data that helps us understand, explain and work to amplify those benefits.

Our data shows how underfunding basic research, especially in high-priority areas, poses a real threat to the United States’ role as a leader in critical technology areas, forestalls innovation and makes it harder to recruit the skilled workers that high-tech companies need to succeed.

A promised investment

Less than two years ago, in August 2022, university researchers like me had reason to celebrate.

Congress had just passed the bipartisan CHIPS and Science Act. The science part of the law promised one of the biggest federal investments in the National Science Foundation in its 74-year history.

The CHIPS act authorized US$81 billion for the agency, promised to double its budget by 2027 and directed it to “address societal, national, and geostrategic challenges for the benefit of all Americans” by investing in research.

But there was one very big snag. The money still has to be appropriated by Congress every year. Lawmakers haven’t been good at doing that recently. As lawmakers struggle to keep the lights on, fundamental research is quickly becoming a casualty of political dysfunction.

Research’s critical impact

That’s bad because fundamental research matters in more ways than you might expect.

For instance, the basic discoveries that made the COVID-19 vaccine possible stretch back to the early 1960s. Such research investments contribute to the health, wealth and well-being of society, support jobs and regional economies and are vital to the U.S. economy and national security.

Lagging research investment will hurt U.S. leadership in critical technologies such as artificial intelligence, advanced communications, clean energy and biotechnology. Less support means less new research work gets done, fewer new researchers are trained and important new discoveries are made elsewhere.

But disrupting federal research funding also directly affects people’s jobs, lives and the economy.

Businesses nationwide thrive by selling the goods and services – everything from pipettes and biological specimens to notebooks and plane tickets – that are necessary for research. Those vendors include high-tech startups, manufacturers, contractors and even Main Street businesses like your local hardware store. They employ your neighbors and friends and contribute to the economic health of your hometown and the nation.

Nearly a third of the $10 billion in federal research funds that 26 of the universities in our consortium used in 2022 directly supported U.S. employers, including:

  • A Detroit welding shop that sells gases many labs use in experiments funded by the National Institutes of Health, National Science Foundation, Department of Defense and Department of Energy.

  • A Dallas-based construction company that is building an advanced vaccine and drug development facility paid for by the Department of Health and Human Services.

  • More than a dozen Utah businesses, including surveyors, engineers and construction and trucking companies, working on a Department of Energy project to develop breakthroughs in geothermal energy.

When Congress shortchanges basic research, it also damages businesses like these and people you might not usually associate with academic science and engineering. Construction and manufacturing companies earn more than $2 billion each year from federally funded research done by our consortium’s members.

Jobs and innovation

Disrupting or decreasing research funding also slows the flow of STEM – science, technology, engineering and math – talent from universities to American businesses. Highly trained people are essential to corporate innovation and to U.S. leadership in key fields, such as AI, where companies depend on hiring to secure research expertise.

In 2022, federal research grants paid wages for about 122,500 people at universities that shared data with my institute. More than half of them were students or trainees. Our data shows that they go on to many types of jobs but are particularly important for leading tech companies such as Google, Amazon, Apple, Facebook and Intel.

That same data lets me estimate that over 300,000 people who worked at U.S. universities in 2022 were paid by federal research funds. Threats to federal research investments put academic jobs at risk. They also hurt private sector innovation because even the most successful companies need to hire people with expert research skills. Most people learn those skills by working on university research projects, and most of those projects are federally funded.

High stakes

If Congress doesn’t move to fund fundamental science research to meet CHIPS and Science Act targets – and make up for the $11.6 billion it’s already behind schedule – the long-term consequences for American competitiveness could be serious.

Over time, companies would see fewer skilled job candidates, and academic and corporate researchers would produce fewer discoveries. Fewer high-tech startups would mean slower economic growth. America would become less competitive in the age of AI. This would turn one of the fears that led lawmakers to pass the CHIPS and Science Act into a reality.

Ultimately, it’s up to lawmakers to decide whether to fulfill their promise to invest more in the research that supports jobs across the economy and in American innovation, competitiveness and economic growth. So far, that promise is looking pretty fragile.
