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.
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.
