Eastern Fence Lizard is a species of spiny lizard native to the eastern US and eastern Mississippi. Based on phylogenetic evidence, this species was delineated from other species in the greater United States, and ranges in eastern MS and beyond to the east coast (Leaché, 2009). In coastal Mississippi they intergrade with prairie lizards, and may not be distinguishable through traditional morphological characters. Sceloporus undulatus is brown or gray with a with dark, wavy crossbands on the back. Adult males are not as patterned but have bright blue belly and throat markings. They are generally found in forest habitats. Exact delineations of the Prairie and the Eastern Fence Lizard ranges are unclear.
