Flippers entwined in a courtly embrace, two seals perform an underwater version of Strictly Come Dancing.
And their graceful routines win top marks from the judges - in this case crowds of Christmas holidaymakers.
The one-year-old pair of common seals arrived at the North Carolina Zoological Park in April and soon became a hit with staff and visitors through their aquatic displays.

Before long they had been nicknamed Fred and Ginger, after Astaire and Rogers.
'When I approached their pool and saw them swimming and dancing together like this I really got excited,' said zoo volunteer Valerie Abbott, who took this picture.
'I just watched their patterns for a few minutes and then started shooting with my camera.
'These two can always be seen dancing together around their exhibit - they are really a lot of fun to watch.'

The secret of the perfect dancing partnership, in this case at least, seems to be a healthy diet based largely on seafood.
'They eat fish and lots of it,' added Miss Abbott.
'They get some in the morning and then in the afternoon they go through a training exercise where they are rewarded with more fish.'
Taking a break: Even dancing seals need to get away from the limelight sometimes
