The blunt-nosed leopard lizard (Gambelia sila) is a relatively large lizard of the Crotaphytidae family. It has a long, regenerative tail, long, powerful hind limbs, and a short, blunt snout. Adult males are slightly larger than females, ranging in size from 3.4 to 4.7 inches (120 mm) in length, excluding tail. Females are 3.4 to 4.4 inches (110 mm) long. Males weigh 1.3 to 1.5 ounces, females 0.8 to 1.2.
Blunt-nosed leopard lizards feed primarily on insects particularly grasshoppers, crickets, moths, and other lizards and occasionally plant material.
Although blunt-nosed leopard lizards are darker than other leopard lizards, they exhibit tremendous variation in color and pattern on their backs. Their background color ranges from yellowish or light gray-brown to dark brown, depending on the surrounding soil color and vegetation. Their undersides are uniformly white. They have rows of dark spots across their backs, alternating with white, cream-colored or yellow bands.
