<P> The New Mexico whiptail lizard is a crossbreed of a western whiptail , which lives in the desert , and the little striped whiptail , which favours grasslands . The lizard is a female - only species that reproduces by producing an egg through parthenogenesis . Despite reproducing asexually , and being an all - female species , the whiptail still engages in mating behavior with other females of its own species , giving rise to the common nickname `` lesbian lizards '' . A common theory is that this behavior stimulates ovulation , as those that do not `` mate '' do not lay eggs . </P>
what type of reproduction do whiptail lizards use
parthenogenesis
