"Marsupials" Natural Recordings by Native Speakers
Marsupials are a group of mammals that give birth to underdeveloped young, which then complete their development inside a pouch on their mother's body.
A marsupial is a mammal that gives birth to underdeveloped young, which then complete their development inside a pouch on their mother's body. This pouch, called a marsupium, provides a safe and nourishing environment for the young to grow and develop. Marsupials are found primarily in Australia, New Guinea, and nearby islands, and include kangaroos, koalas, opossums, and wombats.
Marsupialisation refers to the process of giving birth to underdeveloped young, which then continue to develop outside the mother's body, receiving nourishment from a yolk sac or from a milk-like substance produced by the mother, as in the case of marsupials, such as kangaroos and opossums. In contrast, placental mammals, such as humans and most other mammals, give birth to relatively developed young that receive nourishment from the placenta while in the womb.
