Eve, the rare hooded seal, has been a major attraction for visitors visiting the seal sanctuary in Skegness since she arrived in December last year.
Now, as her future hangs in the balance, James Webster reports on the international row that means she could be banned from returning to her home waters of Iceland.
One of the keepers who has been responsible for feeding Eve says they have been giving her plenty of fish and weighing her every day to make sure she has built up enough blubber to help her survive her cold home waters. Simon Ashburn says she was very underweight when she arrived at Natureland.
Officials on Iceland have turned away a rescued seal which is currently being cared for at a seal sanctuary in Lincolnshire. Staff at Natureland in Skegness have spent recent months nursing Eve back to health after she was found near Chapel St Leonards.
The animal is almost ready to be released back into the wild and the sanctuary hold she cold be taken back to Icelandic waters, close to where it is thought she was born. But officials there say they will not accept her because of the risk of infection.
Eve was first picked up by rescuers in Germany last August. A tracker on her showed she then swam to Scotland but instead of heading north she travelled down the east coast. Natureland staff are now trying to decide what to do with her.
