Males of most species are territorial, defending a space that includes the home ranges or territories of several females. Under such "resource defense polygyny," a male mates with most females residing within his territory. Males typically engage in territorial displays with other males, either head bobbing or using an extendable dewlap.
All agamids lay eggs, except for a few species of high-latitude northern Eurasian Phrynocephalus, which are live-bearers. (Cophotis may also be a live-bearer, but this has not been confirmed.) Small species have small clutch sizes, but some larger species lay more than a dozen eggs. Some agamids lay several clutches of eggs during a growing season.
