An unusually high number of the largest known species of jellyfish have been spotted off the west coast this year.

Figures from the National Biodiversity Data centre show there have been 157 recorded sightings of the Lion’s Mane jellyfish in Kerry, Clare, Galway, Mayo, Sligo, and Donegal.

According to the Irish Examiner, marine scientists are at a loss to explain why this is happening this year.


Jellyfish expert, Damien Haberlin of UCC says up until about two years ago, there weren’t many Lion’s Mane jellyfish seen on the west coast; they were restricted to the Irish Sea.
