By Laura Klappenbach. Monotremes (Monotremata) are a unique group of mammals that lay eggs instead of giving birth to live young like other mammals (such as placental mammals and marsupials). Monotremes include several species of echidnas and the platypus.Monotremes differ from other mammals in that they have a singoe opening for their urinary, digestive and reproductive tracts (this single opening is known as a cloaca and is similar to the anatomy of reptiles).onotremes lay eggs and like other mammals lactate (produce milk) but instead of having nipples like other mammals, monotremes secrete milk through mammary gland openings in the skin. Adult monotremes do not have any teeth. Monotremes are long-lived mammals.
