Seven sharks are to move 60 miles from their current home to a temporary tank - and the sea life centre's staff are not looking forward to the operation.
The sharks will be taken to Great Yarmouth
The sharks live at the sea life centre in Hunstanton, Norfolk, but their tank needs cleaning and refurbishing.
Staff will put the sharks in a transporter tank to be taken to Great Yarmouth where they will be kept until the work is carried out.
Nigel Croasdale, from the centre, said it is a potentially dangerous job.
He said: "I wouldn't advise anyone not experienced in handling fish or sharks to do it because it would probably be dangerous.
"But for our people experienced in moving sharks it should be quite a straightforward operation.
"As long as they treat the creatures with a great deal of respect and care it should go smoothly.
"It's only going to take the sharks about 24 hours in their new surroundings to start feeding again.
"So by the time we're ready to move them back they'll have forgotten their current tank in Hunstanton."
