An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own; at which point the animal hatches.
An egg results from fertilization of an ovum.
Most arthropods, vertebrates, and mollusks lay eggs, although some, such as scorpions and most mammals, do not.
