Divers 'awestruck' as they encounter a monster jellyfish 'as big as them' off the Cornish coast.

This incredible video shows a diver off the British coast swimming with a huge barrel jellyfish that was 'as big as her'.
Dan Abbott was filming marine life around the coast with biologist Lizzie Daly, host of BBC Earth. On the last leg of their tour of the British Isles, the duo went for a dip off the coast of Falmouth, Cornwall, and spotted the massive jellyfish. Dan continued: 'The thing that this whole week has been about is demonstrating that you don't need to go to the other side of the world to see amazing marine wildlife, there's plenty on our doorstep.'It was myself and Lizzie Daly, that's the person in the photo, we travelled all around the UK to various different marine hot spots.'The final leg was in Cornwall where we went for a dive where we encountered the enormous barrel jellyfish.' Cornwall was nice and warm for diving, and because of the jellyfish that was my favourite part but it's all been good, each one has been very special..' During their trip, Dan and Lizzie raised money for the Marine Conservation Society. Pictures and footage they collected will be uploaded onto Lizzie's social media channels.
