A mum has issued a warning after being "surrounded" by jellyfish in seconds on the beach, with some "bigger than her head".
Kate Lally, 33, was stunned to see dozens of the creatures wash up on the sand after going for a stroll along Formby Beach on Wednesday, May 31.
She wasn't paying attention as she walked with her headphones in, before almost stepping on one, which she said was one of the largest jellyfish she'd ever seen.
