Before you go swimming in Britain's calm waters read this!

For, just when you thought it was safe, this picture shows just how dangerous our seas can be.

If young Jonathan Asplin had not been wearing a wetsuit he might not be alive to tell his holiday tale, after being stung by what is thought to be a jellyfish.

The eight-year-old Horsmonden Primary School pupil is believed to have been stung by a Man O'War jellyfish while playing in rock pools on a holiday in north Devon.

His mother Carolyn Asplin, from Horsmonden, said her son was in excruciating pain.

“He was hopping, he couldn’t put any weight on the foot at all and he was just screaming 'get me to the hospital, I need a doctor,’ then on the way to the hospital he just kept saying 'it’s going purple.’”
