Giant jellyfish as big as diver spotted off UK coast
A giant jellyfish have been spotted off the coast of Cornwall. Lizzie Daly came across the huge barrel jellyfish while diving near Falmouth on Saturday. She said the sea creature was as big as her body and that the largest of its kind that she had seen.
It is the largest species of jellyfish which is found in British waters, with the average diameter being about 40 cm.
Lizzie Daly, a TV presenter, and a conservationist was diving for the Wild Ocean Week campaign, which helps funds for the Marine Conservation Society.
The sea creatures have been spotted washing up on the shores of Cornwall recently, with one wildlife enthusiast telling Cornwall Live he has seen more barrel jellyfish in the last three days than in last 15 years combined.
He also said that the jellyfish he has seen lately is a lot bigger than ones spotted previously.
This number of any other jellyfish is not unusual, but barrel jellyfish is so big that this is really quite a phenomenon. Their bell can be two foot across and they can weigh in at over 30kgs.
Their appearance seems to have coincided with a plankton bloom (upside which they feast) that has probably been caused by the sunny weather.
