What is the difference between the 3 types of development: Oviparous, Oviviparous, and Viviparous?
Oviparous development = offspring develop in an egg hatched outside the mother's body
Oviviparous development = offspring develop in an egg hatched inside the mother's body
Viviparous development = offspring receive nutrients from the mother's placenta
