Platypuses
Platypuses live in Australia/and they are mammals. Usually,/mammals bear babies/and raise them with milk. 例 In contrast,/platypuses lay eggs. The eggs hatch in about ten days,/then mothers give milk to their babies. Scientists say/that this was common for ancient mammals. In other words,/platypuses are “living fossils.”
Australia is isolated from other continents/and platypuses could escape from many enemies. In addition,/they live in rivers for protection,/so platypuses have survived until today.
