Jellyfish in Cockle Pond and boating lake

Gosport Borough Council has issued a statement to reassure visitors to the Cockle Pond and boating lake in Walpole Park.

A spokesperson said: "These areas of water are classified as saline lagoons, which are rare habitats.

"The jellyfish now being seen are moon jellyfish (scientific name Aurelia aurita) which are common and are generally seen in harbours and estuaries. They live in brackish water with a low salt content.

"Their sting is not strong enough to penetrate human skin, but it's important to be cautious, as people's sensitivity can vary and some individuals could have some irritation."
