Parthenogenesis, a form of asexual reproduction, is explored across various species including goblin spiders, sharks, rays, amphibians, crocodilians, and squamate reptiles. This reproductive strategy allows organisms to produce offspring without male fertilization, raising questions about genetic diversity and adaptability. Notable instances in captive environments and the evolutionary implications of parthenogenesis in ancient reptiles are discussed, alongside research on the New Mexico whiptail lizard.
