viviparous

Bearing living young

Viviparous describes animals that give birth to live young rather than laying eggs.

The offspring develop inside the mother's body and are nourished there until birth.

Most mammals are viviparous, as are some reptiles, fish, and insects.

The term contrasts with oviparous (egg-laying) and ovoviviparous (eggs that hatch internally).
