The spiny anteaters, or echidnas, make up four of the five species in the order Monotremata. These are primitive mammals that lay eggs like reptiles, but have hair and suckle their young.
Is a spiny anteater a placental mammal?
Mammals can be divided into three more groups based on how their babies develop. These three groups are monotremes, marsupials, and the largest group, placental mammals. Monotremes are mammals that lay eggs. The only monotremes that are alive today are the spiny anteater, or echidna, and the platypus.

anteater, (suborder Vermilingua), any of four species of toothless, insect-eating mammals found in tropical savannas and forests from southern Mexico to Paraguay and northern Argentina. They are long-tailed animals with elongated skulls and tubular muzzles.

Echidnas, also called spiny anteaters, are walking contradictions. They are mammals, but they lay eggs. They are often classified as long- or sort-beaked, but don’t have beaks at all, in the traditional sense; they have fleshy noses that can be either on the long side or rather short.

Was the common ancestor of platypus and echidnas a venomous monotreme?
Molecular data show that the main component of platypus venom emerged before the divergence of platypus and echidnas, suggesting that the most recent common ancestor of these taxa was also possibly a venomous monotreme. Monotremes synthesize L- ascorbic acid only in the kidneys.
