Desert grassland whiptail lizard
The Desert Grassland Whiptail lizard (Aspidoscelis uniparens) is an all-female species. It was formerly placed in the genus Cnemidophorus. A. uniparens have limited social stimuli, having only two basic needs: finding food and avoiding predators.A common predator of the whiptail lizard is the leopard lizard, who prey on A. uniparens by using ambush and stalking hunting tactics.These reptiles reproduce by parthenogenesis; eggs undergo a chromosome doubling after meiosis and develop into lizards without being fertilized. However, ovulation is enhanced by female-female courtship and "mating" (pseudocopulation) rituals that resemble the behavior of closely related to species that reproduce sexually. However, this claim has been disputed, as Collins and Pinch relate.
