The unicorns of the sea, Monodon monoceros are members of the order Cetacea, along with whales, dolphins and porpoises.

身为洋中的独角兽，它们与鲸鱼、鼠一样，属于鲸类纲。

As the turtle swims across the oceanarium,the first porpoise swoops down from above and butts his shell with his belly.

在另一次戏中，当水族馆时，第一只从上方猛扑下去，并用腹部撞击壳。
