Taxonomy
editSome sources consider the gray checkered whiptail to be a subspecies of the common checkered whiptail, Aspidoscelis tesselatus,[2] whereas others grant it full species status.[1] It is one of many lizard species known to be parthenogenetic.[2]
Etymology
editThe epithet, dixoni, is in homage of renowned American herpetologist James R. Dixon,[3]
Description
editThe gray checkered whiptail grows to between 20 and 30 centimetres (8 and 12 in) in total length (including tail). It is typically gray in color, with 10–12 white or yellow stripes that go the length of the body, often with spotting or checkering on the stripes. It is thin-bodied, with a long tail.[citation needed]
Behavior and diet
editLike most whiptail lizards, the gray checkered whiptail is diurnal and insectivorous. It is wary, energetic, and fast moving, darting for cover if approached.[citation needed]
Habitat
editThe preferred habitat of A. dixoni is rocky, semi-arid areas with sparse vegetation.[citation needed]
Reproduction
editA. dixoni is parthenogenic, females lay unfertilized eggs in the mid-summer, which hatch in approximately six weeks.[citation needed]
