We all know what a pain jellyfish can be for young and old. Even though the sea is their natural habitat, we complain when we see them at the beach… so how many complaints would there be if we were to see a giant jellyfish like the one that was spotted off the coast of Cornwall?

Lizzie Daly came across the huge barrel jellyfish while diving near Falmouth. She said the sea creature was as big as her body and the largest of its kind that she had seen.

Barrel jellyfish are the largest species of jellyfish found in UK waters. They normally gravitated towards warmer coastal warmers in late spring and often wash up on British beaches in May or June, sometimes in their hundreds, according to The Wildlife Trusts.

They get their nickname of “dustbin-lid jellyfish” from the fact they can grow to the size of a dustbin lid. Their sting is not usually harmful to humans, but they can still sting when dead.
