A jellyfish, the size of a human, was spotted by divers off the coast of Cornwall on Saturday. A video and photo of the giant jellyfish were shared on social media.

Lizzie Daly, a biologist who was diving near Falmouth, came across the massive ocean creature which was as big as her whole body.

According to reports, the sea creature — identified as a barrel jellyfish — is the largest species of jellyfish found in British waters. It can be found washed ashore in summer and autumn when they swarm off the coast. The species is also known as a dustbin-lid jellyfish.

“What an unforgettable experience, I know barrel jellyfish get really big in size but I have never seen anything like it before,” Daly, who was filming as part of Wild Ocean Week, posted on Instagram.

Rupert Kirkwood, a Cornish marine enthusiast known as The Lone Kayaker, wrote on his blog: “There are more barrel jellyfish around the coast of SW England than I have ever seen in 15-plus years of sea kayaking. A lot more... I have seen more in the last three days than all the other years added together … 91 on Tuesday, 120+ on Wednesday and 40+ today."

“This number of any other jellyfish is not unusual, but barrel jellyfish are so BIG that this is really quite a phenomenon. Their ‘bell’ can be two foot across and they can weigh in at over 30kgs (66 pounds)... Their appearance seems to have coincided with a plankton bloom (upon which they feast) that has probably been caused by the sunny weather," he added.
