I purchased alot of $1 dvds at Walmart yesterday. Most of them were ocean documentaries. I thought they were going to be cheesy, but turned out to have alot of interesting footage.
In one particular documentary, called "Shark Quest", a couple of free-divers in Australia chum and attract a large tiger shark. It was a female, and appeared to have a distended stomach (pregnant maybe?). Anyways, the shark turned very aggressive, and started circling the divers, making lunges at them. So the divers got out of the water, and removed the chum buckets.
After the tiger shark calmed down and left the surface, the divers reentered the water. A reef shark (blacktip I think) showed up too. As the divers were filming, the tiger shark grabbed the reef shark by the tail, and began to slowly devour it alive. With the reef shark at a 90 degree angle on its side, the tiger shark slowly but methodically worked its way up until finally only the reef sharks head remained.
A few observations from me. It appeared that the reef shark may have been undergoing some tonic immobility, even from just being on its side. Secondly, tiger sharks appear to be more aggressive either when they are pregnant, or when divers lack scuba gear. Perhaps exhaust bubbles from scuba gear make the sharks more wary.
