Many different types of animals lay eggs. It is not possible to list them all. Insects, most fish, amphibians, birds, and reptiles all lay eggs, as do many others. Some mammals - namely the platypus and the echidna - also lay eggs.
Usually a cat lays around. I've seen one that happy and fat.
Animals that lay eggs don't have belly buttons

Some animals lay more eggs because of larger penises = simple method bigger willy more fertilization.
OK, not an aquatic animal, but...When damselfly's go under the water's surface to lay eggs, they trap an air bubble around them to breathe.
They probably lay some where around 3 or 4SOMETIMES THEY LAY 1 OR 2 IT DEPENDS
I'm not sure, but I think it's because some animals have breasts, while some don't. The ones with breasts can give their babies milk, and maybe that's why they don't lay eggs. I have no idea! D:
