I the mammal is a monotreme, it developes in an egg. If the mammal is in the marsupial group, it develops in a pouch on its mother. If it is a placental mammal, it develops in the placenta.
yes of course the baby of mammals develop in eggs inside mother. Here the fertilization will be internal. There are some egg laying mammals also......such as platypus and Pygmy shrew.
mammals have milk for their baby
One of the main differences is independence ! Most baby mammals require sustenance from the mother in order to grow and develop (like puppies, kittens, baby pigs etc suckling from the mother animal) - Baby reptiles are completely independent from the moment they're hatched (or born) - and quickly go off in search of their first meal.
Baby mammals cannot reproduce, they have to be mature.
Placental mammals and marsupials develop in a placenta within the uterus before being delivered. Monotremes develop in an egg.
They did not. Mammals evolved independently of birds.
All seals, including baby harp seals, are mammals.
Yes. All caribou are mammals.
chicken

fluuckck you science
Marsupials are mammals with a pouch. A female marsupial gives birth to a very tiny baby, which climbs into a pouch on its mother's belly. Then the baby nurses and continues to grow until it's large enough it doesn't need the pouch for protection.
