Animals that lay eggs are known as oviparous animals and include fish, birds, reptiles and insects. These types of animals have little to no other development within the mother.

The platypus is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species appear in the fossil record. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving
Bacteria and other tiny cells merely divide in two to reproduce, but more complex creatures need more complex means of reproduction. Animals use eggs in one form or other; however, most are not very similar to the familiar breakfast food many of us enjoy. Animal eggs are as different and varied in their structure as the animals who made them.
The egg is the organic vessel containing the zygote in which an embryo develops until it can survive on its own; at which point the animal hatches. An egg results from fertilization of an egg cell. Most arthropods, vertebrates (excluding mammals), and mollusks lay eggs, although some, such as scorpions do not.
