All mammals look after their young. Mammals are characterised by the fact that they nurture their young on mothers' milk, aning his necessitates looking are their young for a period of anywhere from a few weeks to many months.
Your question seems to suggest that mammals that feed milk to their young are a subset of mammals. But all mammals feed milk to their young. That, along with the presence of hair, is the defining characteristic of all mammals, without exceptions.
Yes, they are mammals. All mammals, except the platypus, have live young.
No, not all mammals breastfeed their young. Some mammals, like monotremes (such as platypuses and echidnas), lay eggs and do not produce milk to feed their offspring.
All mammals suckle their young. That is one of the defining characteristics that makes them mammals. Even egg-laying mammals (monotremes which include the platypus and echidna) suckle their young.
Yes. Kangaroos are marsupials, which are a sub-group of mammals. All mammals suckle their young.
Yes, all mammals are warmblooded vertebrates.Yes, all mammals are warm blooded vertebrates. So are birds. The difference between birds and mammals is that birds have feathers and lay eggs, while most mammals give birth to live young, and all mammals have hair and produce milk for their young.
There are no cold blooded mammals.
they are living
Echidnas are mammals, despite being egg-laying mammals, or monotremes. Therefore, like all mammals, they feed their young on mothers' milk.
All mammals, with the exception of monotremes (egg-laying mammals) give birth to live young.
Like all mammals, platypus young feed on mothers' milk. The platypus and echidna are both egg-laying mammals, but they are still classified as mammals because the young suckle from the mother.
All mammals suckle their young ones.
