Walkers on Tramore beach are being asked to keep their eyes peeled as several Portugese Man O'War jellyfish have been spotted washed up on the beach over the last few days.
They look like a small inflated blue balloon. They do not die when washed ashore, they are still able to sting and their sting is excruciatingly painful.
Water Safety Ireland says walkers should mind curious children and dogs.
Chairperson of Water Safety Ireland Waterford Lola O'Sullivan explains they can give you an extremely painful sting:
"People need to be extremely careful...the tentacles will really cause problems for dogs and children.
"We would normally wash any tentacles off with water, either seawater or ordinary water. If it became severe after 30-40 minutes, then seek medical attention."
Lola advises that a stung dog should be brought to the vet.
