Editing Chuckwalla (section)

== Description ==
Chuckwallas are stocky, wide-bodied lizards with flattened midsections and prominent bellies. Their tails are thick, tapering to a blunt tip.<ref name=Stebbins/> Loose folds of skin characterize the neck and sides of their bodies, which are covered in small, coarsely granular scales. The [[Sauromalus ater|common chuckwalla]] (''Sauromalus ater'') measures {{nobr|15.75 inches}} long, whereas insular species such as the [[San Esteban chuckwalla]] of [[San Esteban Island]] (''Sauromalus varius'') can measure as long as  {{nobr|30 inches.}}

They are [[Sexual dimorphism|sexually dimorphic]], with males having reddish-pink to orange, yellow, or light gray bodies and black heads, shoulders, and limbs; females and juveniles have bodies with scattered spots or contrasting bands of light and dark in shades of gray or yellow. Males are generally larger than females and possess well-developed [[femoral pore]]s located on the inner sides of their thighs; these pores produce secretions believed to play a role in marking [[territory (animal)|territory]].<ref name=Stebbins/>
