Usually, seeing one or two small jellyfish is enough to keep you out of the water for a while. Now imagine seeing this giant barrel jellyfish off the coast of Cornwall in the UK. Barrel jellyfish are the largest jellyfish found in the Atlantic Ocean, and this one was even more imposing than its brethren.
Lizzie Daly, a biologist who spotted the jellyfish near Falmouth, said, “I’ve never seen one that big. We had seen a few smaller jellyfish at a beautiful reef nearby, and then out of the murk came this huge, beautiful jellyfish. You just take a double look and ask yourself if it’s actually a meter and a half long.”
