Hundreds of jellyfish have been spotted in the waters of a boating lake in Gosport.

Visitors to the Cockle Pond and boating lake in Walpole Park have been surprised to see the new inhabitants.

Shocking photos show the scale of the moon jellyfish, with several captured in one photograph alone.

Although it is not confirmed how they ended up in the park’s waters, people have been assured that they do not sting.

A spokesperson from Gosport Borough Council 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."

According to the Hampshire and Isle of Wight Wildlife Trust (HIWWT), the moon jelly is the most common jellyfish in UK seas, often washing up on our beaches.

They can be identified by their round, dome-shaped jelly, translucent with four purple circular markings around the centre.

The moon jelly is also seen floating just below the surface of the water.

They typically live for around six months.
