Giant jellyfish almost as big as diver spotted off Cornwall coast

A jellyfish apparently the size of a human was spotted off the coast of southwest England, and a stunning video shows the marine creature swimming by divers.

The giant barrel jellyfish was found swimming Saturday near Falmouth when Lizzie Daly, a biologist and ambassador for the United Kingdom’s Marine Conservation Society, and underwater cameraman Dan Abbott were diving.

The two were finishing up their expedition, Wild Ocean Week – an effort to raise awareness and money for the conservation group – when the jellyfish appeared.

“It was breathtaking,” Daly told USA TODAY. “We had been diving for about half an hour, and out of the murky water was this single enormous jellyfish.”

Daly said she and Abbott swam with the marine creature for about an hour.Â

While seeing these jellyfish off Cornwall’s coast is not uncommon during the summer months as waters warm in the area, Daly said she had never swam with one this large. She estimates it was almost 5 feet long, about as tall as she is.

“It was very humbling to be swimming alongside of it,” she said. The animal isn’t a threat to humans and has only a mild sting, she added. “It was just a pretty majestic creature.”Â

Mind of an octopus

Mind of an octopus

The remarkable distributed nervous system of the octopus is discussed at an astrobiology conference.

Unlike vertebrates, two-thirds of an octopus’ neurons are in its tentacles. Tentacles respond to the surrounding environment without help from the head’s brain. If something this weird is here on our own Earth, what could be out there in space?

The venue at which Dominic Sivitilli shares his latest research on octopuses is telling enough: an astrobiology conference, AbSciCon2019. At this year’s event, the University of Washington doctoral student describes details that he’s learned on how octopuses gather information, make decisions, and even think.

The behavioral psychologist’s intent? To highlight how the creatures’ decentralized nervous systems are a stunning example of the diversity of forms in which extraterrestrial intelligence may, someday, be encountered.
