1.5-metre jellyfish spotted off coast of Cornwall

Divers stayed close to giant animal for an hour before it swam away

A giant barrel jellyfish has been spotted off the coast of Cornwall by divers.

"I've never seen one that big," said Lizzie Daly, a biologist who saw the creature near Falmouth. "We had seen a few smaller jellyfish at a beautiful reef nearby, and then out of the murk came this huge, beautiful jelly fish. You just take a double look and ask yourself if it's actually a metre and a half long."
