What would you do if you were out on your stand up paddle board and you found yourself surrounded by Great White Sharks?
If you're anything like us, you'd probably panic and paddle the hell out of there as quickly as possible.
But not these guys. Instead they decide to stick their oars in (literally!) and film the creatures swimming underneath and around them.
We can't work out whether this is brave, foolish or both, but it makes for a damn cool video.
