Closely related to the tree lizard (Urosaurus ornatus), the Long-tailed Brush Lizard may be distinguished from its congeneric relative by the prominent dark longitudinal markings across the dorsum and its over-sized tail- many times doubling its own body length.
Urosaurus graciosus appears to have the ability (at some level) to withstand introduced/invasive tree species.
In Arizona Urosaurus graciosus shannoni, the Arizona brush lizard, is found.

Abstract: The reproductive characteristics of Urosaurus nigricaudus at El Comitán, Baja California Sur, México, were determined through the necropsy of 33 males and 60 females during 1992.
The average size of clutch per female was 4.06 ± 1.86 eggs; 3.58 eggs for the first clutch and 4.75 eggs for the second clutch.
Urosaurus nigricaudus gonads and fat-body masses of the males and females.

Following Darwin, my hypothesis is that these sexually dimorphic traits in Urosaurus ornatus expose individuals to greater risk of predation.
The male tree lizard, Urosaurus ornatus, has sexually dimorphic coloration that it displays conspicuously to females.
The range of the expression of coloration is used here to test the risk of predation on Urosaurus ornatus.

The spermatozoa of Uta stansburian a and Urosaurus ornatus show the following squamate autapomorphies: a single perforatorium extending anteriorly from the apical tip of the paracrystalline subacrosomal cone; the presence of an epinuclear electron lucent region; intermitochondrial dense bodies; and the fibrous sheath extending into the midpiece.
The acrosome vesicle is flattened and concentrically zoned apically; basally it overlies a subacrosomal cone which invests the nuclear rostrum.
The sperm of Uta and Urosaurus show strong similarities to those of the agamids and polychrotids.

The colors of these two treatments were based on the approximate natural extremes of the lizards’ environment.
