Detailed explanation-1: -They are viviparous animals. They produce living young instead of eggs from within the body. Examples include common lizard (Zootoca vivipara), Phrynosomatidae lizard.

Detailed explanation-2: -oviparous-fish, frogs, hen, sparrow, lizard, butterfly.

Detailed explanation-3: –The lizard that can give birth to a young one i.e. which shows viviparity is Zootoca vivipara or also called common lizard. It is a Eurasian lizard and most of the populations are viviparous. The word Zootoca and vivipara means live birth.

Detailed explanation-4: -The common lizard (Zootoca vivipara) is one of very few known reproductively bimodal species, in which some populations are oviparous and others viviparous.

Detailed explanation-5: -Most lizards reproduce by laying eggs. In some small species, the number of eggs is rather uniform for each laying or clutch. For example, all anoles (Anolis) lay but a single egg at a time, many geckos lay one or two eggs (depending upon the species), and some skinks have clutches of two eggs.
