A warning has been issued to visitors of a popular beach after some dangerous jellyfish were discovered.
Richard Lee was walking alongside Traeth Lligwy, near Moelfre, Wales, when he came upon several Lion's mane jellyfish. While the sting from this particular species of jellyfish are rarely lethal, they can cause severe skin reactions that feel like a really bad nettle rash.
If someone gets stung by a Lion's mane jellyfish, North Wales Wildlife Trust (NWWT) advises to go see a doctor if symptoms become particularly severe. The sea creature gets its name from its red-orange cluster of tentacles that can reach astonishing lengths, North Wales Live reports.
