Orca (also known as Killer Whales) are known to use complex tactics in order to capture prey. This video displays a fine example of cooperation and planning to obtain some food...
I feel a bit sorry for the seal, but that is the way of nature. What I find unique about this tactic is that only one whale benefits from a meal, while the others do the grunt work. I wonder if they take turns at getting the prize?
