Spiny lizrd

Cincinnati Zoo

Some spiny blue lizards (Sceloporus serrifer cyanogenys) 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.
