A second Portuguese Man-o'-War jellyfish has been washed up alive on a Cornish beach within two days.

It was discovered stranded on Porthmeor Beach, St Ives, on Wednesday - in the same location where the first one was found on Monday.

It is the seventh recording of a potentially-dangerous Portuguese Man-o'-War in UK waters since 2003.

Experts from the Marine Conservation Society said it was possible that more of the creatures would be washed up.

The latest specimen is now on display in a special tank at the Blue Reef Aquarium in Newquay.

Hydrozoans

Blue Reef's David Waines said: "To find one of these amazing creatures in the UK is extremely unusual.

"To have two turn up in the space of a few days on the same beach is extraordinary.

"Experts believe the continued onshore winds must have blown them onto the coast and that there may well be more on the way.

"We're feeding our specimen mysis shrimps and keeping it in a secure tank so that it poses no threat to visitors," he added.

Although commonly known as jellyfish, they are actually floating colonies of closely-related animals called hydrozoans - small and plant-shaped, with a stalk and tentacles.

These tentacles are used to catch fish and other marine life and then paralyse or kill them with their powerful stings.

Anyone who comes into contact with the tentacles usually receives painful stings which leave red lesions and ulcerations.

However, some swimmers have died from a sting after going into severe anaphylactic shock.

Anyone stung should immediately remove any tentacles and immerse the affected area in either hot or iced water for 20 minutes.

Vinegar should not be used as it can make the sting worse.
