河马

Hippopotamuses teem in this river.

这条河里有很多河。

The long-toed bird—a jacana, or lily trotter—can walk atop floating plants, as the half-hidden jacana next to the hippo is doing.

这只长脚水雉鸟可以像图中这个只漏半个头的河，在水中植物上行走。

For years, the hippo has been the leading candidate for the closest land relative because of its similar DNA and whalelike features.

多年来河直是主要的陆地最近亲动物的表，因为河有其相似的DNA以及有鲸类特征。
