The class Mammalia is divided into two subclasses based on reproductive techniques: egg-laying mammals (yinotherians or monotremes - see also Australosphenida), and mammals which give live birth . The latter subclass is divided into two infraclasses: pouched mammals ( metatherians or marsupials ), and placental mammals ( eutherians , for which ...
Monotremes (/ ˈ m ɒ n ə t r iː m z /) are mammals of the order Monotremata.They are the only group of living mammals that lay eggs, rather than bearing live young.The extant monotreme species are the platypus and the four species of echidnas.
Other monotremes also have developed the ability to electrolocate, but the platypus is the best at it among the monotremes. While the echidna species has 400 to 2,000 electroreceptor skin cells ...
Ornithorhynchoidea is a superfamily of mammals containing the only living monotremes, the platypus and the echidnas, as well as their closest fossil relatives, to the exclusion of more primitive fossil monotremes of uncertain affinity.
The four extant species of echidnas and the platypus are the only living mammals that lay eggs and the only surviving members of the order Monotremata. [3] The diet of some species consists of ants and termites, but they are not closely related to the American true anteaters or to hedgehogs. Their young are called puggles.

These Australian mammals are part of a mostly-extinct group of mammals known as monotremes that have some un-mammalish habits. For example, laying eggs! However, like other good mammal mothers ...
Australia is home to two of the five extant species of monotremes and the majority of the world's marsupials (the remainder are from Papua New Guinea, eastern Indonesia and the Americas). The taxonomy is somewhat fluid; this list generally follows Menkhorst and Knight [ 1 ] and Van Dyck and Strahan, [ 2 ] with some input from the global list ...
