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.

Marsupials give live birth to undeveloped young, which then crawl to the nipples (protected by a pouch in many species). Monotremes lay eggs and do not have nipples. Adult marsupials have teeth, but adult monotremes are toothless. Monotremes have interclavicle and coracoid bones in their shoulders, putting their legs to the sides of their bodies like reptiles. Marsupials do not. Monotremes have spurs on their ankles (venomous only for male platypuses), but marsupials do not.
