Platypuses are one of two types of mammals which develop from eggs. The mother platypus prepares a chamber at the end of a burrow especially for the purpose of protecting the young. After she lays one to three eggs, which have already developed within her body for 28 days, she curls her body around the eggs to incubate them for another ten days.
After hatching, the mother platypus feeds her young on milk secreted from glands, rather than from teats. The young are blind, hairless and completely vulnerable. They are suckled by the mother for 3-4 months, during which time she only leaves them to forage for food. As she leaves the burrow, the mother platypus makes several thin plugs made of soil along the length of burrow; this helps to protect the young from predators which would enter the burrow during the mother's absence. When she returns, she pushes past these plugs, thereby forcing water from her fur and helping to keep the chamber dry.
No. Platypuses are not placental mammals, but monotremes, meaning that they reproduce by laying eggs. The young do not develop in the mother's womb, and therefore do not receive their nutrition via an umbilical cord.
No. Platypuses do not have a pouch. Marsupials are the mammals characterised (for the most part) by a pouch on the female's abdomen. Platypuses are monotremes, and do not have a pouch. admittedly, the other monotreme, the echidna, does develop a rudimentary pouch during the breeding season, but the platypus does not.
No. America does not have platypuses. Platypuses are endemic to eastern Australia.
