SEVERAL of the UK’S largest species of native jellyfish have washed up on a Sussex beach.

Barrel Jellyfish, which can grow up to 90cm in diameter and weigh as much as 35kg, have been spotted on beaches in Arun.

A spokesman for Arun District Council said a “small number” had been seen this week.

But he reassured resident that their sting was “too weak to hurt humans”.

The spokesman said: “Though jellyfish are infamous for their stinging tentacles, most species are harmless to humans.

“They may leave a rash and cause a nettle type sting if touched. Several jellyfish visit UK waters.

“Barrel jellyfish feed entirely on tiny plankton, so their sting is too weak to hurt humans.

“So, the advice is to look but not touch and keep dogs well away from them.

“They will naturally biodegrade and/or be eaten by other marine life if left alone.

“Treatment for stings is normally to rinse the affected area thoroughly then apply vinegar followed by antihistamine or hydrocortisone creams.”
