Placentals, marsupials and monotremes are all types of mammals. Therefore, the main thing which they all have in common is that they all feed their young on mothers' milk.
In addition, they are all warm blooded vertebrates with a covering of fur, skin or hair. They all have four-chambered hearts, and full circulatory, respiratory and digestive systems. They all have a flexible neck with seven cervical vertebrae, and show enhanced neocortex development. Their limbs are oriented vertically and they produce sound via the larynx.
