As one of the most【C1】_________predators (食肉动物), killer whales may not fit the【C2】_________of a cultured creature.

        Like humans, killer whales have colonized a range of different【C8】_________across the globe, occupying every ocean basin on the planet with an empire that【C9】_________from pole to pole. As such, different populations of killer whales have had to learn different hunting techniques in order to gain the upper hand over their local prey (猎物).
