"This occurs in most mammals, some cartilaginous fish, and a few reptiles, making this animals viviparous.

Internal Fertilization : has the advantage of protecting the fertilized egg on land. The embryo is isolated within the female, which limits predation on the young.

External Fertilization : is benificial because the mother does not have to physically carry the developing offspring and it is a male organism's sperm fertilizing a female's organism's egg outside of the female's body."
