What Is a Mammal?: Different Kinds of Mammals

The video tutorial explores the diversity of mammals, highlighting three main groups: monotremes, marsupials, and placental mammals. Monotremes, like the spiny anteater and duck-billed platypus, are unique for laying eggs. Marsupials, such as kangaroos and opossums, give birth to live young that develop in a pouch. Placental mammals, the largest group, develop inside the mother's body and are born live. Examples include cats, dogs, and humans. The video also discusses specific groups within placental mammals, like hoofed animals, rodents, and carnivores.
