Animals that give birth directly to young ones?

Answer 1

An animal that gives live birth is called viviparous. This means that the young develop inside the mother and gain some nourishment from the mother, before being born. There is usually a placenta surrounding the young, through which nutrients get to the young and wastes leave the young. There are some animals that develop inside the mother, but within eggs. They gain nourishment from the egg yolk rather than from the mother. The eggs hatch inside the mother just before the young are delivered. These animals are called ovoviviparous. In mammals, marsupials and placental mammals are viviparous (marsupials have less advanced placentas), while monotremes are oviparous (lay eggs). There are no ovoviviparous mammals. Some non-mammalian viviparous animals are scorpions, velvet worms, some sharks, some snakes, and some lizards.
