Portuguese man o’ war on the rise in UK and Irish seas

The Portuguese man o’ war has seen a significant rise in sightings in UK and Irish seas over the past year. This increase could be due to rising sea temperatures and strong winds pushing them to the coast. Although these creatures are not true jellyfish, their growing presence may indicate changes in the marine ecosystem. New scuba divers should be aware of this species when exploring underwater, as their stings can be harmful.
