Kade Tame, 26, and Devon, 28, from Cape Town, saw a superpod of dolphins
The two brothers had been fishing just off Fish Hoek in False Bay, South Africa
They incredibly saw a frenzy of hundreds of dolphins devouring a shoal of fish
Amazing footage shows the dolphins being joined by three humpback whales
Businessman Kade said the feeding frenzy saw their 18-foot boat spin in circles
