A group of eight Portuguese Man O’ War were found strewn on Tregantle beach near Whitsand Bay. Experts say they expect more to be brought in by prevailing winds. Daily Telegraph. These creatures, which are not actually jellyfish but a species called siphonophores, live in warmer waters than those around the UK but global warming is believed to be pushing them further north – ever closer towards Britain. They can in extreme cases provoke a cardiac arrest and death in particularly sensitive persons.
It is also interesting note that Portuguese Man O’ War have also been seen increasingly more often on the coasts of Spain.
Note the English and Spanish etymology comes from the creature’s air bladder, which looks similar to the triangular sails of the 15th.century Portuguese man-of-war Caravela latina.
