Are puffer fish born alive or in a egg?

Pufferfish are born from eggs. They are oviparous, meaning they lay eggs.

Here's a bit more information:

* Eggs: Pufferfish eggs are usually small and round, and are laid in clusters attached to seaweed or other underwater vegetation.

* Hatching: After a few days or weeks, depending on the species and water temperature, the eggs hatch into tiny larvae.

* Larvae: These larvae are very different from adult pufferfish, and they have a different diet and lifestyle.

* Growth: Over time, the larvae undergo a metamorphosis, gradually developing the characteristic features of adult pufferfish, including their spines and the ability to inflate themselves.

So, while pufferfish are not born live, they do start their lives in the water, encased within a protective egg.
