The common name of this genus is derived from the lizards’ ability to run at impressive speeds; some species can run almost 28 km (17 miles) per hour over short distances.​ They generally prefer open habitats where direct exposure to the sun is available. Racerunners are highly active lizards that search widely for prey, using their tongues to sample chemicals in the environment and a highly sensitive organ to discriminate prey based on chemical cues. Their diet consists mainly of spiders and insects.

Description

  • Aspidoscelis deppii is a medium-sized whiptail lizard in the family Teiidae, commonly called the tiger whiptail. It has a slender body, long powerful hind legs, a narrow head, and a long tail. Adults are typically brown, olive, or grey with several pale longitudinal stripes and darker markings, while juveniles are more strongly patterned, often with vivid blue or greenish tones on the tail and body.

Range

  • Aspidoscelis deppii occurs from western and southern Mexico through Central America to Panama. In Mexico, it is widespread along the Pacific and southern regions, including Guerrero and the Zihuatanejo area.

Habitat

  • It inhabits tropical dry forest, thorn scrub, woodland, grassland, savanna, forest edges, clearings, agricultural areas, and disturbed ground. It is strongly terrestrial and is frequently seen basking or rapidly foraging across sunny open ground.

Diet

  • Aspidoscelis deppii is an active, opportunistic predator that feeds primarily on insects and other arthropods, including ants, termites, beetles, grasshoppers, caterpillars, spiders, and other small invertebrates. It may also consume small vertebrates, eggs, fruit, or other available food.
