The youngsters stay with the parents until they are independent - this can be anywhere from a few months to many years.
they keep the young by thereside. remember bottle-nosed dolphins are mammals
Placental Mammals.
Koalas and Kangaroos belong to the group of animals known as Marsupials. These mammals are characterized by having special pouches in which they keep their young.
Placental mammals retain their young within the body of the mother for a long period of time. Humans, dogs, bears, and mice are all examples of placental mammals.Mammals which do not retain their young for a long period of time are marsupials, all of which have short gestation periods (e.g. kangaroos, koalas, Tasmanian devils, wombats, etc) and monotremes (platypuses and echidnas), which are egg-laying mammals.
Yes, mammals care for their young.
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.
All mammals, with the exception of the monotremes, give birth to live young. Monotremes are egg-laying mammals, and comprise just three species: platypus, short-beaked echidna and long-beaked echidna.
Quite simply, there are three species of mammals which lay eggs rather than giving birth to live young. These are the platypus, the short-beaked achidna and the long-beaked echidna. These mammals are still classified as mammals because they have fur, breathe using lungs and feed their young on mothers' milk. The last characteristic is the defining characteristic of all mammals, regardless of whether they are placental mammals, marsupials or monotremes (egg-laying mammals).
Yes. Kangaroos are marsupials, which are a sub-group of mammals. All mammals suckle their young.
Mammals give birth to their young for purposes of procreation. This is what ensures that the life cycle of the mammals is continued.
Chipmunks do not lay eggs, they are mammals and give birth to live young.
Monotremes are mammals which lay eggs, as opposed to all other mammals which give birth to live young. The only mammals which are monotremes are the platypus and short-beaked echidna of Australia, and the long-beaked echidna of New Guinea.
