Parthenogenesis, is a form of asexual reproduction where an egg develops into an organism without fertilization. It occurs commonly among lower plants and invertebrate animals (particularly rotifers, aphids, ants, wasps, and bees) and rarely among higher vertebrates.

Parthenogenesis takes place spontaneously in rotifers, nematodes, aphids, as well as other invertebrates and plants. Among vertebrates, birds, snakes, sharks, and lizards are the only species that can reproduce by strict parthenogenesis. While other amphibians, fish, and reptiles can perform different forms of hybridogenesis, which is a form of incomplete parthenogenesis.

All frogs reproduce sexually, and all hatch from eggs.In almost all frogs, egg fertilization happens outside the female's body instead of inside. The female releases her eggs and the male releases his sperm at the same time.
