Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land.

The embryo is isolated within the female, which limits predation on the young.

Internalfertilization also enhances the fertilization of eggs by a specific male.

Even though fewer offspring are produced through this method, their survival rate is higher than that for external fertilization.
