World Jellyfish Day

World Jellyfish Day

Yesterday marks World Jellyfish Day, and we’re not ones to turn down an opportunity to talk about jellies! We’ve rounded up some of the jellyfish you’re most likely to spot on the UK coastline and share how you can get involved in our Jellyfish Survey.

To date, thousands of people have shared sightings of jellyfish from around the UK, helping to build an extensive data set of six jellyfish and two jellyfish-like hydrozoan species. Understanding trends in jellyfish distribution and numbers can help us understand where leatherback turtle feeding grounds might be, as well as potentially indicating the impacts of climate change on our ocean. Most adult jellyfish have died off in the UK autumn months, but some species, including the Portuguese Man ‘o War are still around – so watch out when you are on the beach this month….

Dr Peter Richardson, Head of Ocean Recovery: “Through our online jellyfish survey, we’ve been receiving reports of Portuguese Man of War on beaches in south Wales in September. Through October we’ve continued to receive reports of them appearing on beaches in Devon and Cornwall, with mass strandings in Cornwall this weekend. The weather will be blowing them in from the Atlantic as part of another major Portuguese Man of War stranding event - the last one was in similar conditions in 2017 and they seem to be getting more frequent since we started our survey in 2003.”

“We urge beachgoers not to touch them…they pack a very powerful sting! But, please do report them on our website so we can better understand the extent of this stranding event.”
