The research, published in the high-profile scientific journal Proceedings of the Royal Society (B) was conducted in collaboration with colleagues at Swansea University, the Coastal and Marine Research Centre at UCC, the Marine Biological Association of the UK and the University of Plymouth.

School of BEES PhD student Thomas Bastian and CMRC researcher Tom Doyle, led the Irish contribution to the research.

"It's quite exciting working with those barrel jellyfish (up to 3kg) and both Thomas and I are now heading up a UCC led tracking study that will quantify both vertical and horizontal movements of the venomous lion's mane jellyfish in Dublin Bay," said Doyle.
