河马

Hippopotamuses teem in this river.

这条河里有很多河马。

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河马，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.

多年来河马直是主要陆地最近亲动物代表，因为河马有其相似DNA以及有鲸类特征。
