Former England cricketers David Lloyd and Nasser Hussain decided to go shark diving ahead of the second Ashes Test in Australia.
The Sky Sports commentators, who are Down Under for the return Ashes series with England, were lowered into the water at Port Lincoln in a cage to get closer to the sharks.
Lloyd wrote in the Daily Mail: "One of them came within a couple of metres of my cage, so I thought it best not to stick my hand out and stroke him on the nose.
"Nasser preferred not to go in a second time. I think they might have taken one look at his hooter and sensed a kindred spirit."
