Genus Cnemidophorus, commonly referred to as whiptail lizards, belongs to the family Teiidae. These lizards inhabit many regions throughout North and South America, including deserts, grasslands, and forests. Some synonyms for this genus include Aspidocnemus, Cnemiidophorus, and Teius. The whiptail lizard is known for its distinctive long tail that often exceeds its body length. This genus is unique in that it consists entirely of female-only species that reproduce through parthenogenesis, a type of asexual reproduction. These lizards are important contributors to their ecosystems, where they are both predators and prey for a variety of other animals.
