n.河马（hippopotamus的复数形式）

An order of hooved mammals of the subclass Eutheria (including pigs and peccaries and hippopotami and members of the suborder Ruminantia) having an even number of functional toes. 有蹄哺乳动物的一目，属于真兽亚纲（包含猪、野猪、河马和反刍亚目的成员），功能脚趾为偶数。

Once we came across a school of hippopotami, which rose, and bellowed dreadfully at us within ten or a dozen fathoms of the boat. 有一次我们遇到一群河马，离我们的船有十至十二码的样子，正一沉一浮地怪叫着朝我们游来，样子十分可怕。

Visitors may have the opportunity to enjoy seeing with their own eyes giant animals such as Elephants and Hippopotami devour their food ravenously. 最近隆重推出"动物进食大观"和"猴山新貌"等项目，游客们可亲眼目睹河马狂张大口、大象巧用长鼻和狼吞虎咽的情景。

And wallowing in the water holes and dams, you'll spot the ears and eyes of hippopotami which weigh between 200 and 300kg (441 and 661lbs). 你还会看到在池塘和水库中打滚的河马露出的耳朵和眼睛，它们重200到300公斤（441到661磅）。

some hippopotami. 好几头河马。
