Dolphins perfect bubble rings underwater

SeaWorld has revealed amazing footage of dolphins blowing bubble rings out of their blowholes.
They are captured blowing puffs of air and angling their heads so that they rise in a straight line thereby creating the perfect circles.
The underwater mammals from Sea World Orlando's Dolphin Cove are shown playing with the large bubble rings and spinning them around with their noses. They also bite into them to create smaller circles.
'It's a cool behaviour the dolphins seem to learn from one another,' one trainer said.
Another said it was the 'most incredible thing' he had ever seen.

Most of the playful mammals who display the behaviour are females. This may be because males are preoccupied with socialising with eachother.
SeaWorld has kept dolphins for more than 30 years, but one trainer said they were still surprising them.
'Just when you think you've seen it all, something new comes up,' he said.
'These animals have alot more to teach us.'
