Sea swimmers warned over dangerous jellyfish
Dublin bathers enjoying a seaside dip have been urged to be cautious due to the presence of dangerous jellyfish in the water.
Lion's Mane jellyfish have been spotted in the waters around Sandycove and other areas along the coast in south Dublin.
The jellyfish can grow up to 50cm in diameter and have long hair-like tentacles that can cause a severe sting to swimmers.
Dún Laoghaire-Rathdown County Council has erected warning signs in affected areas.
In addition, lifeguard warning flags are on red and will remain so until further notice.
Lifeguards are also on duty in the area.
Earlier this week, Irish Water Safety issued a warning about Lion's Mane jellyfish around the Ard an Rátha area of Co Donegal.
In 2014, 17 of the venomous jellyfish were washed up at Sandycove.
