What do a platypus and a waratah have in common?

Beyond both being mammals, coyotes and platypuses have nothing more in common. They are both warm-blooded vertebrates, covered in fur, which bathe air using lungs, and that feed their young on mothers' milk. This is where the similarities end.

Platypuses are monotremes, or egg-laying mammals, while coyotes are eutherians, or placental mammals. They do not have the same diet or hunting habits, and they do not even live on the same continent.
