Do guppies carry their babies in mouth?

Guppies are a type of livebearer, which means that they give birth to live young instead of laying eggs. However, they do not carry their babies in their mouths. The female guppy has a special reproductive organ called the gonopodium that is used to fertilize the eggs internally. After the eggs are fertilized, they develop inside the female's body until they are ready to be born. At that time, the female guppy will give birth to live young that are fully formed and able to swim on their own.
