« BackLargest infestation of Portuguese Men O’War in 100 years anticipated along Kerry coastline

portugese man o warIrish Water Safety is advising people to exercise caution in coming days as an influx of Portuguese Men O’War is expected on Kerry coasts.

Prevailing southerly winds, tropical air and high sea temperatures has led to an increase in these jellyfish-like creatures from Spanish and African waters.

The new moon and spring tides on Saturday could increase the numbers even further.

A sting from a Portuguese Man-O-War leaves a red welt on the skin and in some cases can induce an allergic reaction or even anaphylactic shock.

Animal Curator with Dingle Oceanworld Louise Overy says it’s important to rinse the affected area with sea-water or warm water:


The jellyfish-like creatures have already been identified on  Slea Head, off the Blasket Islands, in Ballybunion and along the South Kerry coastline.

Sightings of Portuguese Men O’War should be reported to Kerry County Council’s Water Safety department at 066-7183662.
