Officials in Maine have issued warnings to beachgoers following the appearance of a nearly five-foot-wide lion’s mane jellyfish washed ashore over the weekend. The large sea creature has prompted advisories to avoid contact due to its potentially harmful sting. Increased sightings of lion’s mane jellyfish have led multiple coastal towns in Maine to issue jellyfish warnings. The lion’s mane jellyfish, noted for its striking appearance, has become a new concern for swimmers and visitors along the New England coast. Similar jellyfish occurrences have been reported in other regions, including hundreds of jellyfish found on a beach in Oost-Vlieland. Additionally, a jellyfish sting incident was reported at a beach in Jeju, South Korea, highlighting the broader impact of jellyfish in coastal areas during the current season.
