Record attempt: Simone Arrigoni is pushed along by the dolphins as he recorded 13 underwater circuits
As he is pushed along underwater, this diver shows how he is in perfect tune with two dolphins.
But this performance isn't part of a marine show - it is actually a record attempt.
Simone Arrigoni completed 13 circuits under dolphin power - and broke his own record - using the dynamic apnea technique, which involves holding your breath.
Pushed along: The dolphins, named Paco and Marco, completed the circuits, or 'voltas', in 1 minute 53 seconds
The attempt took place at a marine centre in the Italian town of Tovaianica, south of Rome.
Arrigoni completed the circuits, or 'voltas' as he calls them, in one minute 53 seconds - and travelled 657 metres.
'Voltas' is a Portuguese term used by the diver to define the circles that he constructs as he is pushed along by the dolphins - in this case, Paco and Marco.
The task is made more difficult as it requires absolute synchronisation with the animals.
And the dolphins are required to surface at least twice during the test in order to breathe, while the diver remains under the surface in a fixed position.

Arrigoni said before the attempt: 'The trainers at Zoomarine have taught to me to listen to the dolphins and that they converse with each other in order to correct the position during the test.'
This is the third year that Arrigoni has attempted to complete the challenge.
Previously he had set a record using the technique when he completed 12 'voltas', or 607 metres, in a total of one minute 42 seconds.
