Some species of the whiptail lizard consist of only females – there are no males!

The females use parthenogenesis to reproduce in which they lay unfertilised eggs that hatch into parthenogenetic females. Though parthenogenesis exists in other animals such as bees and aphids, it’s rare in vertebrates. The all-female species have originated through hybridisation or breeding between species.
