You’re probably wondering, "Do boa constrictors lay eggs?"

The answer is no! Boa constrictors are one of the few snake species that give birth to live young.

This is thanks to a process called ovoviviparity.

This means the embryos develop inside the mother’s body, nourished by a yolk sac, and emerge as fully formed mini-snakes.

But why no eggs? It’s likely due to the evolutionary benefits of live birth, like increased survival rates and better parental care.
