The term for animals that are born alive instead of hatching from eggs is "viviparous." Viviparous species develop their young internally, receiving nourishment directly from their mother during gestation. This method of reproduction is commonly seen in mammals, including humans, dogs, and whales. Viviparous animals can provide more protection to the developing young compared to egg-laying methods, as the young are often born in a more advanced state of development. This process is in contrast to oviparous species, which lay eggs that hatch outside the mother's body.
