Spiny lizards are so-called because their scales are large, strongly keeled (ridged) and pointy -- altogether kind of "spiny." The blue spiny lizard is the biggest of the bunch, growing up to 14 inches or more, including the tail.

Some blue spiny lizards are bluer than others. All have blue shoulders; beyond that, females are usually fairly drab in color. Males have a metallic blue-green sheen on the back, and their chin, throat and belly are also blue. Both males and females have a very distinct black-and-white collar around the neck.

Blue spiny lizards are diurnal, meaning they're active during the day. They eat a variety of invertebrates, though they seem to favor flying insects. When they're not foraging, the lizards spend a lot of time sheltering underground or in rocky crevices, avoiding temperature extremes or hiding from predators.

From February to June, females give birth to live young. Litters may contain as few as six or as many as 18 little lizards.
