Deadly sea creature washes up on UK coastline as beachgoers warned over heatwave dips

Potentally deadly creatures have washed up along the British coastline sparking a warning for swimmers to take care during heatwave dips.

Beachgoers were left stunned after swarms of the venomous jellyfish-like Portuguese man o’ war were spotted along the Cornish coast.

Brits are flocking to the seaside as the UK experiences record temperatures across the country with highs of 40 degrees in some areas.

However, some have been left panicking rather than relaxing after the stunning creatures were found washed up on the beach.

The animals, which are commonly mistaken for jellyfish, are known to exude a painful venom used to paralysed and kill small fish.

The sting can be excrutiatingly painful to humans and there have been rare occasions when swimmers have died after getting caught up in its long, thin tendrils, that can extend 165 feet in length below the surface

A local community conservation group has taken to social media to share pictures of the sea creature in a bid to warn locals.

In the post, they reported that 12 people were left stranded along the picturesque Portheras Cove in Cornwall due to the creature’s arrival.

In a further warning to water users, dog walkers and beach-goers, they expressed the importance to be vigilant as they can still sting despite being stranded on sand.

As the neurotoxin they produce can cause severe problems, especially around the eyes and airways, they have stressed it’s vital not to touch them.

While they are beautiful creatures, coloured blue, pink and purple, they are best admired from a distance.

Users shared their shock in the comments, as many couldn’t believe that something so “stunning” could be so dangerous.

“A shame something so pretty can be dangerous,” one person said.

“Pretty but not really very likeable,” another commented

“So beautiful,” a third said while another called them “”nasty beasties.”

Portuguese man o’war have been spotted on British shores several times so far this year.

The enormous creatures, also known as the man of war, can grow tentacles measuring up to 160ft which is equivalent to the size of around five double decker buses.

While rare, with just 62 reported UK sightings in the last year, strong tides and windy weather can see them wash up on our beaches.

Children and elderly people are particularly at risk from their unsuspecting stings.
