育儿袋

Having no marsupial pouch, the mother presses the patagium into service.

但它有像有袋物一样的育儿袋，这时猫猴妈妈的翼膜就派上用场了。

Many species have a pouch (marsupium), a fold of skin covering the nipples on the mother's lower belly, where the young continue their development.

许多品种都有一个育儿袋（marsupium），在母体下腹盖住乳头的皮袋，幼体在袋内继续发育。
