Answer:

Ornithorhynchus differs from Macropus as the former​ is an Oviparous mammal.

Explanation:

• Ornithorhynchus or Platypus is an oviparous mammal whereas Macropus or Kangaroo is a viviparous mammal.
• Mammals give birth to their young ones and are termed as viviparous but Platypus and Echidna are the exceptions as they lay eggs.
• Macropus or Kangaroo is a marsupial, i.e. they give birth to premature young ones which continue the development while staying attached to the nipples on the mother's lower belly.
