The little boy had been visiting the attraction with his mother last month when the whale decided to put on a special display.
The whale mirrored the curious visitor, swimming along before stopping and turning its head with its mouth open to surprise him as the boy froze to match the whale's movements.
Back in 2020, a project from the Sea Life Trust saw two beluga whales, Little Grey and Little White, freed from captivity in China and transferred to an open water sanctuary in the ocean for the first time in more than a decade.
They found that unlike killer whales, which tend to socialise purely along the mother's side of the family, beluga whales frequently mix in large and diverse groups that often extend far beyond simple kinship.
The friendly creature followed the boy along the length of the enclosure as he walked along a raised beam, blowing bubbles and playing with his newfound friend.
