Ovoviviparousanimals develop within eggs that remain within the mother up until they hatch or are about to. This strategy of reproduction is known as ovoviviparity. It is similar to viviparity in that the young are provided with a sheltered environment. However, the young are nourished by the egg yolk rather than the mother's body.

Ovoviviparousreproduction: After fertilization the eggs are not surrounded by a shell but instead immediately develop further into naupliae in the broodpouch of the female.
In one batch of eggs produced in a female all eggs are either cysts or ovoviviparouseggs.
