Wourms and Lombardi listed as advantages of ovoviviparity in fishes these factors: (i) enhanced survival of offspring-notoriously, fish eggs are consumed voraciously by many predators in the open water; (ii) compensation for low fecundity-ovoviviparous species tend to produce fewer eggs but more offspring; (iii) improvement of reproductive .

Fusion of gametes within the body of the female. However, oviparous and viviparous reptiles are common in that prolonged embryonic development increases not only energetic costs but also survival costs due to prolonged exposure of eggs or pregnant females to hostile biotic (such as predators . Although this often leads to a lower number of offspring produced, higher parental investment allows them to have higher survival rates. Advantages and disadvantages associated with oviparity cannot be found in viviparity, and vice versa. Competition between offspring and parents is less. The advantages are something like this :- 1. This is where two or more embryos develop from a single egg, as in the parasitic Hymenoptera, such as braconid, encyrtid, and dryinid wasps. Oviparous and viviparous are such two methods. . Another advantage of ovoviviparity is that the offspring are advanced in their development when they are born live, thus the juveniles are more likely to fend for themselves in the wild.
