This is an incredible video! I was watching the Global Morning News this morning and they had this clip out of South Africa.
Some diving charter (?) was baiting a Great White Shark toward a dive cage with a diver inside. I guess the shark had other ideas and went all Jaws on them. Somehow wrestled itself INTO the CAGE! The shark, being a majestic free spirit of the deep, was nonplussed to be trapped in the cage. The animal thrashed wildly while crew members rushed to open it to let the shark out. It jumped out of the top and swam away. After a few moments, the diver emerged.
The weird part of this story (well weirder than a shark smashing into a dive cage) is that the crew seems confused as to whether someone is in the dive cage.
