A DIVER bit off perhaps more than he could chew when he came into contact with this giant Grouper.
At the beginning of the clip everything looks calm and the diver seems under control, even though the fish is larger than him.
But after a few sudden movements from the diver's cameraman, the Grouper reacts and nips at the diver.
Instinct kicks in, and the diver lands a couple of punches to the large fish before it swims off.
After the incident, the man looks a bit sheepish and starts to head to the boat.
