Under the waves in the English Channel over the weekend, the biologist Lizzie Daly came in person with a huge undersea citizen: a 5-foot-long barrel jellyfish.
Daly was diving near Cornwall, off the coast of the UK, with her associate Dan Abbott, an undersea professional photographer. Abbott snapped an exceptional shot of the cream-colored, almost clear jelly; it was practically as huge as Daly.
“It was spectacular,” Daly, an ambassador for the UK’s Marine Preservation Society, informed U.S.A. Today “We had actually been diving for about half an hour, and out of the dirty water was this single massive jellyfish.”
The jellyfish, whose taxonomic name is Rhizostoma pulmo, is usually safe and typically seen throughout the summer season throughout waters in the UK, along with in the Mediterranean, Adriatic, and Black seas.
It’s the biggest jellyfish types discovered in Britain, however this specific specimen was larger than any Daly or Abbott had actually seen prior to.
“I have actually never ever seen a barrel fish or any jellyfish that huge,” Daly stated in a video that she and Abbott produced about the encounter for Wild Ocean Week. “It was the size of my body.”
Normally, barrel jellies’ mushroom-shaped domed ends (called bells) can reach 3 feet in size. The animal can weigh as much as 77 pounds

Daly informed CBS News that she and Abbott followed the singular jellyfish for about an hour.
“It was extremely humbling to be swimming together with of it,” she stated.
Regardless of its enforcing look and frilly arms, the barrel jellyfish isn’t harmful to human beings or other marine animals; it feeds totally on plankton.
“Barrel jellyfish are safe to us in spite of their size,” the marine biologist Cathy Lucas informed The Guardian “All jellyfish sting, however the barrel sting is weak.”
The jellies’ arms are covered in small stingers (which can even sting after the jelly has actually passed away), however they primarily serve to secure the animal from predators like the leatherback turtle.
“They’re not a danger to human beings,” Daly informed CBS
Jellyfish have actually wandered the oceans for the past 500 million years Made up of 95% water, the animals do not have brains, stomachs, intestinal tracts, or lungs. Rather, nutrients and oxygen slip through their gelatinous layers of transparent skin.
Groups of jellies are called “flowers.”
In the summertimes of 2014 and 2015, UK residents found ratings of barrel-jellyfish flowers near the exact same part of the Cornwall coast where Daly identified her barrel jelly. The jellyfish had actually been drawn close to coast by plankton in warm summer season water, however some cleaned up on the location’s beaches.
Naturally, not all jellyfish are so benign. Some, like package jellyfish envisioned above, can eliminate a human in minutes. Their venom targets the heart and nerve system, and loads such a punch that swimmers can drown or pass away of cardiac arrest prior to reaching coast.
