| Description |
| Size |
| Aspidoscelis tigris as a species is 2 3/8 - 5 inches inches long snout to vent (6 - 12.7 cm), up to around 13 inches (33 cm) total length. |
| Appearance |
Slim-bodied with a long slender tail, a thin snout, and large symmetrical head plates.
The back and sides are grey, tan, or brown, marked with dark spots or bars or mottling, which is often very sharply defined. Dark marks on the sides often form vertical bars. Usually 4 faint light stripes are present along the back. These stripes fade with age.
The belly is made of large, smooth, rectangular scales in 8 lengthwise rows. Often there are reddish patches on the sides of the belly. The throat is pale with with obscure black spots.
Scales on the back are small and granular, and scales on the tail are keeled.
The tail can reach up to two times the length of the body. The tail tip is dark or bluish, and bright blue on juveniles. Juveniles have fairly well-defined stripes.

| Diurnal. Wary and very active, moving with abrupt stops and starts, side-to-side head movement, and tongue flicking. Often seen digging rapidly when foraging. Difficult to approach - typically foraging near cover, and capable of quick bursts of speed into heavy brush or holes. |
| Diet |
| Small invertebrates, especially spiders, scorpions, centipedes, and termites, and small lizards. |
| Reproduction |
| Eggs are laid from April to August and hatch in about a month and a half. |
