Brits have been put on alert after a deadly 100ft-long Portuguese man o’war washed up on a UK beach.
The alien-like creatures, often mistaken for jellyfish, are usually found in tropical oceans – but are increasingly being spotted along British shores.
The animal has a gas-filled float and venomous tentacles.

Experts warn anyone stung should seek immediate medical help.
One was discovered on Porth Trecastell beach, near Caernarfon, north Wales, sparking a warning from coastguards, as reported by Need To Know.
Rhosneigr Coastguard said yesterday (16 Sept): “Visitors enjoying a swim earlier today at our local Porth Trecastell beach happened to come across what looks like a Portuguese man-o’-war washed up on the beach.
“If it is an actual Portuguese man-o’-war then here’s some advice.
“HM Coastguard issues warnings about the presence of the Portuguese man o’ war on beaches, advising the public and dog owners to avoid touching them due to their extremely painful sting, even when the creature is dead.
“Sightings should be reported to the Coastguard, and if stung, severe or lasting pain warrants immediate medical attention.
“These marine organisms, which are siphonophores, not jellyfish, can be carried by currents from warmer Atlantic waters to UK shores, particularly after storms.”
Experts say sightings have become more frequent in recent years, with beachgoers urged to report them immediately.
