I've been stung however

I was foolhardy enough to try to get a beached one back in the water (using gardening gloves & a bit of netting), but got stung on the arms. It was as painful as a nettle sting & lasted about as long. NB it seems(to me) most likely that any sizeable beached jellyfish is paralyzed by the landing & so can't be 'rescued'

NBN Gateway

calls Rhizostoma octopus "Barrel jellyfish". NBN distribution map shows a single 10km square for it in Devon, which happens to be right at the mouth of the Teign estuary, which looks good for your ID.

The images of Rhizostoma octopus

look quite convincing as well. I will retitle this observation.

Incidentally, where there is

Incidentally, where there is an ID posted which you think is correct, just click 'I agree' rather than posting a new ID - it's called 'add a revision' for a reason! If there's a particular reason why you agree, post it in the comments, as you have here

Record your ladybird sightings!
