Cnemidophorus grammicus is a lizard from the Teiidae family. It lives in grassy areas of South America, and all adult individuals are females.
The species is distinguished by the complete absence of males and reproduction without fertilization. It helps control the population of insects in grassy ecosystems.
Immature form that undergoes metamorphosis before adulthood.
