<u>Transient killer whales prey on marine mammals, while resident killer whales prey on Chinook salmon</u>
Explanation:
Remember, the term "ecotypes" is used to refer specifically to the observable differences found in the various kinds of whales, which includes <em>their breeding populations, their language of communication, social structure, the type of food they eat, and their hunting behavior.</em>
Thus, in the case of transient and resident killer whales in the Northeast Pacific, they are thought to represent different ecotypes rather than different species the Transient killer whales prey (feed) on marine mammals, while resident killer whales prey on Chinook salmon. Also, whales are generally thought to belong to the same species.
