Monotreme any member of the egg-laying mammalian order Monotremata which includes the amphibious platypus and the terrestrial echidnas of continental Australia the Australian island state of Tasmania and the island of New Guinea. Like other mammals monotremes are endothermic with a high metabolic rate though not as high as other mammals.

The presence of hair in their bodies three middle ear bones and mammary glands. Mammals have the following characteristics or features. Also when you consider that there are about 1000 species of bats it is not surprising to find that there is considerable room.
