Most female lizards lay eggs. But the females of some species give birth to live young. AnswerParty on!
The reproductive system or genital system is a system of sex organs within an organism which work together for the purpose of reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system.[dead link] Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring.
Gambelia sila, also known as the blunt-nosed leopard lizard, is a blunt nosed lizard found in California.
Gambelia sila was first discovered in 1890 and has since undergone several reclassifications. When it was first discovered by Stejneger in 1890 it was classified as Crotaphytus silus. Stejneger discovered Gambelia sila in Fresno, California. Ten years later in 1900 Cope believed the lizard to be a subspecies of the long-nosed leopard lizard, C. wislizenii, and classified it as C. w. silus. Based on differences in bony plates on the head, the presence or absence of gular folds, and head shape, Gambelia sila was reclassified into the genus Gambelia by Smith in 1946, retaining the species name silus. This is the genus name for leopard lizards in the family Crotaphytidae. Gambelia sila is similar to the lizards in the genus Crotaphytus, the difference is that the latter have fracture planes in their tails. This allows the tails to break off when grasped by predators. This reclassification remained controversial until Montanucci in 1970 proposed the argument for specific classification based on the differences between the long-nosed and blunt-nosed leopard lizards. Eventually the name was changed from "Gambelia silas" to "Gambelia sila" to agree in gender.

The Tropiduridae are a family of iguanid lizards native to South America, including the islands of Trinidad and the Galápagos. Commonly known as Neotropical ground lizards, most are ground-dwelling animals, and the family includes some lizards adapted to relatively cold climates, including those of the Andes mountains and Tierra del Fuego. Several species give birth to live young. Squamata
