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."
She said swimming alongside the "gentle giant" was "such a serene, grounding experience".
Thousands of the creatures, the largest jellyfish found in British coastal waters, flock through the Atlantic Ocean towards warm coastal waters in the west of the UK each year and are often found washed up on beaches across May and June.
Comment: Interestingly around the same time 47 individuals of same species were found beached on St. Simon Island in Georgia.
