Definition:
Ovoviviparous animals produce eggs, but instead of laying the eggs, the eggs develop within the mother's body.
The eggs hatch within the mother and eat unfertilized eggs in the womb for nourishment. Ovoviviparous animals do not have an umbilical cord to attach the embryos to their mother.
Some examples of ovoviviparous include: some sharks (e.g., basking shark) and other fish, snakes and insects.
Examples:
Basking sharks are ovoviviparous and give birth to one or two live young.
