达尔文蛙——用嘴抚育幼儿
Frog(达尔文蛙):The male Darwin frog hatches his eggs in apouch(小袋子,文中指“达尔文蛙的声囊”)in his mouth. He can eat and continue about his business until his tadpoles(蝌蚪)lose their tails, become tiny frogs, and jump out of his mouth!
达尔文蛙见于南美洲大部分地区,它们抚育幼蛙的方式与众不同。达尔文雌蛙产下卵后,雄蛙用舌头把卵卷起咽到声囊里,之后雄性达尔文蛙则继续进食。当蝌蚪长到没有尾巴时,雄蛙便张开嘴,让蝌蚪们跳出去。
奇异的雄海马——生育子女
Sea horse(海马):The male sea horse has a pouch in which the mother lays her eggs. The father then looks after the eggs for about two months, until they hatch and leave the pouch. He continues to protect the young until they are able to live on their own.
相信吗?雄海马可是有孕育子女的能力哦!雄海马腹部有一个小袋,据说可用来装小海马2000只。当雄海马和雌海马交配的时候,雌海马的卵子会巧妙地掉到雄海马的育儿袋里,这些卵子在海马爸爸的腹袋里经过数周后,便会孵化成小海马。
