Order Monotremata

Monotremata is an order from the Mammalia class. This group includes mammals that lay eggs instead of giving birth to live young like marsupials and placental mammals.

CharacteristicsEdit

Like other mammals, monotremes are warm-blooded with a high metabolic rate (though not as high as other mammals; see below); have hair on their bodies; produce milk through mammary glands to feed their young; have a single bone in their lower jaw; and have three middle-ear bones.
