Although hatching usually takes place in 12 to 15 days after fertilization, a delay in hatching may extend this up to 14 additional days. In oviparous reptiles, embryo nourishment comes from the yolk (lecithotrophy). This is necessary because they can lay anywhere between 100-300 eggs at a time (Throughout a female mosquito's life they can lay anywhere between 1000-3000 eggs). What are the advantages and disadvantages of each? On the other hand, in viviparous animals, the development of the egg takes place inside the body of the female. Advantages of Oviparous Reproduction After releasing the egg, oviparous animals are able to continue with daily chores including feeding and locomotion. If we kill animals, then we create a gap in nature’s evolutionary process that can affect the rest of the world. The hatching never occurs inside the womb of the mother. Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is an outmoded term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction.
