Researchers from the University of Pisa recorded dolphins while they were playing in pairs and while playing freely with their human trainers.
The dolphins almost always use the facial expression when they are in their playmate's field of view, the researchers found.
Playmates responded by 'smiling' back a third of the time, and dolphins were more likely to assume the open mouth expression when their faces were in the view of their playmates.
