- Mammals are warm-blooded vertebrates.
- They have a covering of skin or hair/fur.
- All mammals suckle their young with mothers' milk.
- The young of most mammals are born alive, except for monotremes - the platypus and echidna - which lay eggs.
- There are three main groups of mammals: placental, marsupial and monotreme. Monotremes are the egg-laying mammals. Marsupials are characterised by giving birth to undeveloped young which, in most species, must then develop in a pouch.
