Reproduction of reptiles.

Reptiles (or reptiles) come in all shapes and sizes, from tiny geckos to giant dinosaurs. Their reproductive methods and behavior are usually very different from mammals, although there are some similarities. Among reptiles, differences in courtship and breeding rituals can be quite different. Although most reptiles lay eggs like birds, some are viviparous. There are even some female reptiles that do not require males to produce offspring.
