live-bearing

Not laying eggs

Live-bearing describes animals that give birth to developed young rather than laying eggs.

Most mammals are live-bearing, as are some fish, reptiles, and invertebrates.

The technical term is viviparous.

Guppies are popular aquarium fish partly because they're live-bearing and reproduce readily in captivity.
