Monotremes lay their young in eggs.
Platypuses and echidnas are different from other mammals because they are monotremes, i.e. mammals which lay eggs.
Neither. Elephants are placental mammals, which form a different group of mammals from either the marsupials (pouched mammals) or the monotremes (egg-laying mammals).
A platypus IS a mammal. The only difference is that platypuses are egg-laying mammals, or monotremes. In every other sense, they are completely mammals.
Yes monotremes are warm blooded , they are like other mammals
The platypus and the echidna are the only egg-laying mammals, i.e. monotremes.
Monotremes and marsupials are both types of mammals along with placental mammals
Monotremes (Monotremes are primitive, egg-laying mammals)Marsupials (Marsupials are mammals whose babies are born very immature)Placental mammals (Placental mammals are advanced mammals whose unborn young are nourished through a placenta)
Monotremes, marsupials, and placental mammals.
Monotremes are the only mammals that give birth to their young in eggs
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.
Monotremes are extraordinary because they are egg-laying mammals, with the young suckling mothers' milk. Apart from echidnas and platypuses, no other mammals lay eggs.
