Viviparous is a word that describes animals that give birth to live young, rather than laying eggs. It's often used when talking about mammals, like dogs, cats, and humans. So, for example, you could say, "Dolphins are viviparous animals." This means that instead of laying eggs, dolphins carry their babies inside their bodies until they are born alive. You might also hear this word used in science classes or when talking about reproduction in animals.
