A.baleen whales are gentle mammals in the sea

B.baleen whales have a well-developed sense of “smell”

C.baleen whales have baleen to filter food, rather than having teeth

D.baleen whales can’t swim fast due to their colossal size

参考答案：C

参考解析：

细节理解题。根据文章第一段第二句和第三句“Despite their colossal size, they feed on tiny creatures such as krill and zooplankton. That’s because these whales, instead of teeth, have bristle-like structures in their mouth—baleen—which filters out small critters from big gulps of water”可知，尽管它们体型庞大，但它们以磷虾和浮游动物等微小生物为食。这是因为这些鲸鱼不是用牙齿，而是用它们的嘴巴里刚毛状的结构——鲸喙——过滤掉很多的水中的小生物。所以是因为须鲸没有牙齿，所以只能吃微小生物。故选C。
