Divers have swum with a huge barrel jellyfish as big as a human off the coast of Cornwall.

Lizzie Daly, a biologist with Wild Ocean Week, said the creature, spotted off Falmouth, was as big as her body.

It is the largest species of jellyfish found in British waters, with a diameter of up to 90cm and weights of up to 35 kilos.

In summer and autumn they may swarm off the coast, sometimes washing up in large numbers.

Hundreds have been washed up on beaches across Cornwall and Devon this year, with one marine enthusiast, who studies Cornwall’s coastline, saying that he has seen more barrel jellyfish over three days than in the previous 15 years put together.

Rupert Kirkwood, who is known as The Lone Kayaker, wrote on his blog earlier this year: “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.

“Their appearance seems to have coincided with a plankton bloom (upon which they feast) that has probably been caused by the sunny weather.”

He believed there could be “millions” in our waters.
