Because reptiles, birds, and mammals all have amniotic eggs, they are called amniotes. The duck-billed platypus and some other mammals also lay eggs. But most mammals have evolved amniotic eggs that develop inside the mother's womb, or uterus, and so lack a shell.
Do amniotes lay eggs in water?
They are distinguished by a membrane (amnion) protecting the embryo and a lack of a larval stage. Thanks to this, amniotes lay eggs on land or retain them within the mother, unlike anamniotes (fishes and amphibians), which typically lay eggs in water.
What animals have no Amniote eggs?

Most amphibians live part of their lives in the water and part of their lives on the land. Amphibians are four-legged animals that don't have amniotic eggs.
