What is a non-placental mammal?

Answer 1

A mammal is an animal that gives birth to live young and suckles them. A non-mammal is an animal that is born in an egg and does not drink milk from its mother. For example, a bird is a non-mammal because it is born from an egg and does not drink milk. But, there are some exceptions. The duck-billed platypus is one. The platypus is a mammal that suckles its young, but lays eggs!

Answer 2

Non-placental simply means developing from eggs - as opposed to the growing foetus being feed by the mothers placenta. Almost all mammals develop within the mothers body - nourished by the placenta. Birds and most reptiles lay eggs - which feed the growing embryo from a limited supply of yolk.

Answer 3

Most mammal species are placental, but there are several hundred species which are not placentals.

The echidna and the platypus are non-placental mammals. They are monotremes, or egg-laying mammals.

Kangaroos, wallabies, koalas, bandicoots, wombats and Tasmanian devils are just a few other non-placentals, as they are marsupials.

Answer 4

A non mammal is something that is not warm blooded or has no fur or hair and also lays eggs.

also you are a mammal as a bird isn't.

Answer 5

Non-placental mammals include the monotremes, which are egg-laying mammals, and marsupials, which are often referred to as pouched mammals.
