The video shows his stepdad Mott struggling to reel in the six foot bull shark.
Mott said that he has seen a lot of bull sharks at the beach lately and that three weeks ago, he even reeled in eight of them within a few hours.
Experts consider them one of the most dangerous sharks in the world because of their aggressive nature. Sadler told Eyewitness News that his step-father released the bull sharks back into the water.
