Dublin beachgoers warned to watch for lion’s mane jellyfish

Dublin beachgoers are being warned to watch out for Lion’s Mane jellyfish after spotting jellyfish on the capital’s beaches.

Fingal County Council has warned Dubliners that the jellyfish have been spotted on ‘a few of their beaches’ over the past few days.

Fingal County Council said it “urges bathers to be extra vigilant at all of our beaches where Lions Mane jellyfish are found”. They added that when these jellyfish are dead and washed up on the beach, the venom in their tentacles can remain for several days.

They continued, “With so many long trailing tentacles, there’s a chance you could still get stung, even when you try not to swim near them. Additionally, the lion’s mane jellyfish’s tentacle fragments that break loose in the water will sting you, even if they are no longer attached to the jellyfish.

The council insisted that a lion’s mane jellyfish sting can cause nausea, sweating, cramps, headaches and other symptoms. Serious bites may require urgent medical attention. If you find yourself stung by a lion’s mane jellyfish, you should remove any attached tentacles with a gloved hand, towel, or stick.

The area should be rinsed with sea water until you get home, then you can rinse the area in a warm to hot area. It is important to also apply a “dry cold compress” to the bitten area. A dry cold compress is something like ice in a plastic bag, or a vegetable bag, wrapped in a t-shirt or towel. Photo: RollingNews.ie

If you experience symptoms worse than what could be described as “minor discomfort”, medical assistance should be sought. If you have been bitten, you should not rub the area. Alcohol, vinegar and tight bandages are also a no.
