"It is not unusual to see jellyfish in Irish tidal waters this time of year – especially when the water begins to warm up,” said Paul O’Reilly from Inland Fisheries Ireland.

Jellyfish are present in our waters all year round but stay close to the bottom of the sea during winter. Ireland has five indigenous jellyfish species: Barrel, Blue, Common (Moon), Compass, and Lion’s Mane.

The Barrel jellyfish forms enormous blooms every year off Rosslare and Wexford Harbours. The Lion’s Mane jellyfish prefers the cooler waters of the Irish Sea and especially the waters off Dublin.The Lion’s Mane jellyfish is Ireland’s most venomous jellyfish.

While the Barrel Jellyfish can be described as “white, large and meaty”, the Lion’s Mane is small, “flat like a pancake” and its sting is much more painful.

Experts have quashed the urban myth that urine is a miracle cure for stings, with salt-water advised to clear the sting.
