Two divers off the coast of England had the experience of a lifetime when they scientifically came across a human-sized jellyfish – and by their side swam known as Rhizostoma Pulmo.
Diver Lizzie Daly, a biologist, and Dan Abbott, an underwater cameraman, captured the event via live science in front of the camera. Later, Daly recorded the event on Facebook.

The couple, who dived off the coast of Cornwall on Saturday, saw the giant creature after "emerging from the murky waters," Daly told Vice. They then swam with the jellyfish for about an hour.
"It's really modest to be next to an animal of this size," Daly added. "It's an experience we'll never forget."
"My first reaction was that I had never seen a jellyfish of this size in my life," Abbott told the Washington Post about the "beautiful, majestic, slow-moving and graceful animal." ,

Barrel jellyfish are "gentle giants" who "swarm in warmer summers when large plankton blooms provide ample food supplies," Buglife said.
"Their soft bodies are over 90 [percent] of water and move in a mesmerizing pulsating motion that is controlled by a simple network of nerves, although notorious for their stinging tentacles, most species are harmless to humans," He added that the jellyfish is the largest jellyfish found in British waters.
