The last year has seen a record number of jellyfish on our shores, according to a survey by the marine conservation society. It seems if you're on a beach in the Westcountry these days, they're never far away. But why are there so many more of them and are they as dangerous as some people think?
A clip from an interview with Matt Slater, of the Cornwall Wildlife Trust.
The warm weather does bring its share of unwelcome visitors - this last week has seen a surge in the number of monster jellyfish washed up on our shores.
Martin Dowse has been finding out why we're seeing so many of them.
The Marine Conservation Society is warning that warm weather in the south west could bring an influx of giant jellyfish to our coasts. A number of giant barrel jellyfish have already been washed up at Portland and Weymouth.
The species is harmless but the MCS says it's keen to hear from anyone who finds them.
If you've taken a trip to the seaside over recent weeks then you may have noticed jellyfish washed up on the shoreline or in rockpools.
According to the Marine Conservation Society, the creatures have been arriving in ever increasing numbers - and it could be the recent hot weather that's to blame.
Our Environment Correspondent Duncan Sleightholme reports:
An old wives' tale which suggests using urine to treat jellyfish stings has been challenged by the British Red Cross.
The charity instead suggests people treat such stings with salt water or vinegar.
Jellyfish blooms are on the rise following recent warm weather after the cold spring delayed their appearance, marine experts have said. Compass and blue jellyfish have been spotted in the South West.
The Marine Conservation Society (MCS) is urging people to report their sightings of jellyfish, which act as a barometer of the seas, as part of its annual national jellyfish survey.
This year they had been a rare sight in UK seas until hot weather warmed coastal waters in recent weeks. But increasing numbers of moon, compass, blue and lion's mane jellyfish have been reported.
