The lecture and the passage both discuss the nature of shark hunting patterns. The passage claims that shark hunt in groups, and the lecture agrees and supports this claim.

 

First, the passage says that victims of shark attacks were attacked by group of shark. The passage says that a considerable number of victims were reported when being attacked by one shark, and then several showed up to attack the victims. The lecture agrees and states that plenty of evidence confirms there is often more than one shark attacking the victims. The lecture adds that the evidence comes from witnesses and studies of bite wounds on victims.

 

Second, the passage claims that the sharks group-hunt prey in nature. The passage says that by hunting in group, the entire pack gets to eat. Again, the lecture supports this by giving an example of shark hunting baby whales. The lecture says that single shark approach to baby whales and more sharks appeared to attack and eat.

 

To sum up, the passage and the lecture both state that shark hunt in packs. They first say that human were attacked by more than one shark, and then say that the sharks hunt other animals in nature.
