Lesser or Northern Earless Lizard

(Holbrookia m. maculata)
Lesser earless lizards have no external ear openings, which may be an adaptation to this lizard's practice of burrowing headfirst into sand. They can usually be found in a narrow band along extreme southern SD in sandhills, sandy, or gravel-covered areas along streams, as well as plains, and grassland offering an abundance of open space.
Eastern Short-horned Lizard

Eastern Short-horned Lizard

(Phrynosoma douglasi brevirostre)
Short-horned lizards are relatively flat, round lizards with short, stubby horns above the eyes and around the back of the head, and have many small, triangular fringes along the sides of the body. When disturbed by predators, horned lizards occasionally squirt blood from the eyes for distances of up to 2-3 feet. Although it is rare to spot one in SD, there is a population of these lizards in southwestern SD and another in the northwestern part of the state.

Northern Sagebrush Lizard

(Sceloporus g. graciosus)
Named after the sagebrush plants near where it is commonly found, the Sagebrush Lizard is an easily frightened animal that seeks shelter when large animals approach. Due to their skittish nature, these lizards do not typically interact with humans. They are rare in SD but can be found in a small range in the western and southern Black Hills.

The Northern Many-lined Skink is a skinny long-bodied lizard. As its name implies, most many-lined skinks have dark and light stripes that run lengthwise down the body and tail.

(Eumeces septentrionalis)
Found in extreme eastern SD, these small lizards are brown or tan on the back and darker on the sides and have several thin lighter stripes along the sides and the back. They are very secretive and are rarely seen in the open except during their breeding season in spring.
