They are quite well-developed when they come out . The young grow inside their mother´s body , but they aren´t well-developed when they are born . They must continue to develop inside their mother´s puch . They are the most numerous group of mammals. The young grow inside the mother´s body. They are well-developed when they are born. We are placental mammals . We also are members of the primate family , along with chimpanzees and gorillas . We also share this characteristics with them . We have fingers that we can use to manipulate objets . Our eyes are at the front of our head . So we can see straight ahead . We are different because we are bipedal . That means that we walk on two legs . PHOTO HUMAN BEINS In this photo we can see a girl with a monkey. Most platypus live in Australia, others live in Tasmania . Their body is covered with dense, brown fur that traps a layer of insulating air to keep the animal warm . They are carnivores . How many groups of mammals are there? Do monoterms give birth?
