GANSBAAI, South Africa, Nov. 10 (UPI) -- A diver in South Africa captured footage of a great white shark attacking his diving cage while Australian boaters took video of a man attacking a tiger shark.
Canadian Jeremy Stewart was diving off the coast of Gansbaai, South Africa, when a great white shark attacked his diving cage and demonstrated why the area is known as "Shark Alley."
Stewart, who caught the Sept. 30 encounter on video, said the 10-foot-long shark crashed into the cage when it missed a dangling piece of bait.
A less cautious shark encounter was recorded in Australia when a man was dared by his friends to jump onto a tiger shark swimming next to their boat.
"Catch this tiger shark, Brett. I dare you to jump on this tiger shark. Jump up here, come on, it's coming," one of the men says in the video.
The man identified as Brett leaps into the water, splashing down over the shark as his friends laugh.
The other men help Brett back into the boat before the shark comes back around.
Meanwhile, two members of Australia's Adelaide University Scuba Club snapped underwater pictures of a great white shark stalking them as they dove at the Glenelg tyre reef.
Mark Sutcliffe and Jan Busch said the shark circled them three times during their weekend dive before allowing them to return to their boat.
"We waited until it cleared off before exiting the water. Omitted the safety stop on the way up!" Sutcliff posted on Facebook.
