¿Qué es un mamífero?: diferentes tipos de mamíferos

The video tutorial explores the diversity of mammals, highlighting three main groups: Monotremes, Marsupials, and Placental mammals. Monotremes, like echidnas and platypuses, are unique for laying eggs. Marsupials, such as kangaroos and opossums, give birth to underdeveloped young that mature in a pouch. Placental mammals, the largest group, develop inside the mother's body with the help of a placenta. This group includes familiar animals like cats, dogs, and humans. The video also discusses subgroups of placental mammals, including hoofed animals, rodents, and carnivores.
