People urged to keep a lookout for these beautiful stingers along the Wirral coastline

PEOPLE are being urged to keep their eyes open when visiting Wirral’s coastline for beautiful creatures that can sting even when they are dead.

Cheshire Wildlife Trust issued the warning after five Portuguese Man-O-War were found washed up on Walney Island in Cumbria.

There is now every chance they could be found along the Wirral’s shores as they slowly drift through the Irish Sea.

This autumn has seen the highest number of Portuguese Man-O-War strandings for years.

These beautiful jellyfish-like creatures have been washing up on beaches in the South West in their thousands but until now had only been seen as far north as Pembrokeshire in Wales and Dublin in Ireland.

Mike Davis from Barrow, went down to the beach in Cumbria just before sunset when he came across the Portuguese Man-O-War.

Mike said: “At first we just found one, it was about 6 inches long. Then as we continued to walk down the beach we found four smaller ones.

“I’m sure there must be more washed up. It was amazing, we couldn’t believe our eyes!”

These jellyfish-like animals normally live in the open seas but strong and persistent south westerly winds and autumnal storms are causing them to be washed ashore.

Sightings of Portuguese Man-O-War occur every few years in the UK but are rare this far north in the Irish Sea.

Senior Marine Conservation Officer for North West Living Seas, Dr Emily Baxter said: “If they have washed up in Cumbria it is highly likely that they will also appear on other beaches across the North West.”

“These beautiful creatures are not ‘true jellyfish’ but very close relatives of jellyfish, corals and anemones.

“They are siphonophores – a group of highly specialised clones called ‘zooids’ that all work together as one animal.

“They have a bright blue-purple float, shaped like a Cornish pasty, which floats on the sea surface and blue tentacles that hang below the surface, stretching more than 10 metres in length.

“Each of their zooids takes on a different form and function.

“Some are specialised for feeding, some for catching prey and even one for floating.

“They have thousands of stinging cells – little capsules loaded with tiny barbed harpoons – that deliver venom to paralyse and kill their prey (small fish and crustaceans).

“Though it is rarely fatal for humans, their sting can pack a painful punch, so the advise is to look but don’t touch!”

Dr Baxter added: “As the number and distribution of sightings has increased since early September we could see more washing up in the North West, so keep an eye out next time you are out on the shore.

“Although they are beautiful and fascinating, it is important to ensure children and dogs are kept away from any stranded Portuguese Man-O-War as they can still sting even when dead.”

These beautiful stingers play an important role in our ecosystem, providing shelter and protection for small fish.

They are also food for the unusual swimming sea slug and violet sea snails.

With a changing climate and the prospect of more stormy weather, it is also likely that there will be an increase in the frequency of strandings of these open ocean drifters over the coming years.
