Pink belly swift lizards (Sceloporus variabilis) colloquially go by several different names, including pink-bellied swifts and rose-bellied spiny lizards. Native to arid parts of North America from Texas to Costa Rica, these semi-arboreal lizards are agile climbers. They generally grow to between 4 and 6 inches long and can live for upwards of five years, if you take proper care of them.
