⚠️ Heads up beach lovers! ‘Disco’ jellyfish are making waves along Welsh shores! These luminous beauties, known as Mauve stingers, are popping up in large numbers. While they dazzle with their bioluminescent dance moves, they pack a serious sting, earning the nickname “purple people eater”. Ouch!

Recent sightings have been reported at Aberdaron, Trearddur Bay, Traeth Lligwy, and Traeth Llydan. Don’t be fooled by their small size — their hair-like tentacles can stretch up to three meters and are covered in stinging cells, enough to leave you with a burning reminder!

One brave beachgoer at Broad Haven shared her sting story, describing an intense burn that returned overnight even worse. Another account revealed that a young lad stung at Watwick Bay ended up needing antibiotics due to a subsequent infection.

These jellyfish are more commonly found in the Mediterranean, where they clear beaches quicker than a DJ drops beats. Their bioluminescent glow, lighting up in hues of purple to yellow, gives them the apt moniker of “marine disco balls”.
If you’re heading out to the coast, remember to admire these creatures from a distance. The Marine Conservation Society enthuses about their beauty but stresses the importance of keeping safe. And they’re not the only sea creatures to watch out for. The notorious Portuguese Man o’ War has also been making an appearance, so keep your eyes peeled!
The warm weather seems to be influencing these arrivals, with marine heatwaves bringing unusual marine guests. If you encounter these creatures or their more dangerous cousins, the advice is simple: don’t touch! Even washed-up, their sting remains potent.
Let’s keep our beach adventures fun and safe. Respect the ocean and all its dazzling, but sometimes dangerous, inhabitants! 🏖️🌊✨
