The heatwave of 2018 will probably be remembered as the summer of the jellyfish with large and frequent sightings of rare jellyfish becoming the norm across the country.
While walking her two dogs, Ita Shannon, has come across four jellyfish on Beale Strand in Co. Kerry that are so "huge you can see them from far away."
The sting from Lion's Mane jellyfish is not fatal but can be very uncomfortable.
John Leech, Chief Executive of Irish Water Safety says there is a risk that people who are stung could suffer anaphylactic shock.
The public are being asked to report any sightings of Lion's Mane to the National Biodiversity website.
Be careful, lads.
