Birds are not the only animals that lay eggs. Crocodiles and turtles lay eggs. Many insects, frogs, lizards, and snakes lay eggs, too. Some snails and sharks lay eggs. Animals that lay eggs are called oviparous.
Animals that give birth to live young — like humans, dogs, and cats — are called viviparous. There is also a group of animals that are ovoviparous. In ovoviparous animals, young develop in eggs, but hatch inside the body of the mother (or sometimes father) before being born. Cool!

Some mammals also lay eggs. Egg-laying mammals are called monotremes. This cool group of animals includes the platypus and echidnas.
In seahorses, the female lay eggs in the male’s brood pouch. The male ferrtilizes the eggs and incubates them in a special pouch until they are ready to be born. Wow!
Some eggs are so tiny they can only be seen under a microscope, like these from a roundworm parasite, at 400x magnification. The egg on the left contains a young embryo — you can see a ball of cells. The egg on the right shows a well-developed roundworm larva.
