If ever there were a reason to make sure you pick up your litter, take home your unwanted beach toys and leave only footprints, then it is this.
The seal was pictured on a beach in Norfolk by Friends of Horsey Seals.
The organisation tweeted to say it had "finally managed to catch 'Mrs Frisbee'" and that she was on her way to an RSPCA centre near Kings Lynn for removal of the beach toy and some "TLC".
Peter Ansell, the chair of Friends of Horsey Seals, told the BBC: "The image was taken yesterday (Thursday 14th September) but it has been swimming around with the yellow frisbee on its neck for anything up to six months. While it was still healthy and fit, it was in a bunch of seals, one would get spooked and they would all go, which made it hard to capture."
"Over the last few weeks she has deteriorated. We managed to capture her with a net and we took her to the RSPCA centre at East Winch" he continued.
"There is another seal we get reports about with a rope around its next and flipper, another has a rubber tyre around its middle. It's all from litter left in the sea and that's annoying."
Alison Charles, manager RSPCA East Winch wildlife centre, said "she's a lot better than she was, she is alive and eating her fish. We managed to get the item off, her neck is horrendous, I've never seen anything like it."
"It'll take months for it to heal" she said.
Items discarded into the sea, left on beaches at the end of days out or carelessly throw away, pose a real danger to sea life. Birds, mammals and fish can become entrapped in such items, potentially leaving them in life threatening situations.
You can make a difference by taking part in a two minute beach clean, or making sure that you don't leave items behind in the first place.
