The <b>Texas Skink</b> (<i>Holbrookia propinqua</i>) is a slender lizard that thrives in arid habitats of the southwestern U.S. and northern Mexico, featuring smooth scales in light brown to olive green with dark patterns, and plays a crucial role in controlling insect populations. Known for their ability to regulate body temperature through sunbathing and regenerate their tails, these diurnal insectivores are vital to their ecosystem.
