Watson showed the pictures to his wife Sarah as soon as she was out of the water.
Dan's wife, Sally Watson, explained that she wasn't really sure why she was yelling for the children to come out of the water when she told FOX35: "I was at the edge of the water and the kids were standing in the water and I was like, 'Get out, get out, get out.' I didn't know why".
'Thinking my [drone] is now coming with me to every beach day!,' Watson, who is also a videographer with a Youtube channel, posted.
"So, he immediately brings the drone to me and he shows me the frame of the drone and you see that shark swimming right at our kids - it was terrifying".
