Parthenogenesis occurs naturally in some plants, some invertebrate animal species (including nematodes, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea and parasitic wasps) and a few vertebrates (such as some fish,[4] amphibians, reptiles[5][6] and very rarely birds[7]). This type of reproduction has been induced artificially in a few species including fish and amphibians.[8]
