The following video was posted by Sydney Dean and was taken on a cage dive near the Neptune Islands in Australia.
The shark repeatedly attempts to grab the bait but on each occasion, the bait handler yanks it out of reach. As the shark keeps missing the bait, you can almost feel the shark's frustration as it bites at nearby birds that are bobbing about while attempting to pick up scraps.
Unfortunately for the one bird at the 1:00 mark, the shark finally connects and takes it down.
