What is unusual about the method of reproduction in monotremes in mammals?
Monotremes are the only egg-laying mammals. They are fully mammal because they feed their young on mothers' milk. Marsupials are the only mammals to give birth to undeveloped young after a short gestation period. These young are unable to exist independently of their mothers' nourishing teats, and for the most part, they are protected by a pouch, or marsupium - although this is not the case with all marsupials.
Do monotremes have lungs or gills?
