Beachgoers and surfers are being warned about a swarm of poisonous jellyfish which are set to invade Britain's beaches this summer.
According to the Daily Star, bathers were told to look out for the deadly Portuguese man-of-war, which floats just below the water's surface and has stings that can deliver serious injury.
One giant barrel jellyfish has already been washed up at Portland, Dorset, this week and is believed to be one of the first in a surge of the creatures into the seas and beaches around the coast of British beaches.
Fortunately, however, that particular species proved to be harmless to humans.
A predicted warmer than average weather for the UK could bring jellyfish as big as dustbin lids, the Daily Mail reports.
Experts have warned that some of the new jellyfish can sting and anyone affected should get medical attention.
“This predicted hot weather to come can mean that even more jellyfish are likely to wash up or be in the seas around places like the west-country,” Richard Harrington from the Marine Conservation Society said.
“Although this species is harmless their numbers are likely to grow fairly quickly as sea temperatures rise. We are very keen to hear from people that find any washed up anywhere around the country. This is an Atlantic species and are sometimes found washed up but still advise the public not to touch them.”
Local resident Suzanne Sheldon, 48, found the giant jellyfish washed up on the beach earlier this week and reported the find to the MCS and said, “I came across this massive jellyfish as I took my dog for a walk on a quiet beach at Portland, it was at least three feet in width and was very bulky too. It was the largest jellyfish I have ever seen.”
