Animals oviparous and viviparous

                                                                                                                      The animals that are oviparous they are animals that lay eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibiansreptiles, all birds, the monotremes, and most insects, some molluscs and arachnids.                                                     vivipaous vivipary has two different meanings. In animals, it means development of the embryo inside the body of the mother, eventually leading to live birth, as opposed to laying eggs.                          DGM
