Ovoviviparous animals are those that reproduce with eggs that hatch as they are laid or soon afterwards. In an ovoviviparous animal, the eggs are retained inside the mothers' body while they develop. The egg contains all the nutrients that the embryo needs, and there is no direct connection between it and the mother.
This is the reproductive method of some fish, amphibians, reptiles, and invertebrates.
