A video has emerged from the US of two paddle boarders encountering a great white shark.

The footage, captured with a GoPro camera in Santa Barbara, CA, on July 25, shows a huge shark swimming right next to the paddle boarders.

''The great whites are currently penetrating the Central Coastline and we had to check it out at Santa Claus Lane beach,'' the filmer later wrote online.

''The largest shark we saw was at least 8 ft. and the smaller juveniles were probably around 6 feet,'' he added.
