| Genus: Aspidoscelis (formerly Cnemidophorus)
Type of Scales: Smooth, Granular scales Reproduction type: Sexual, females lay 8-12 eggs (Smith 1946). Young Texas Spotted Whiptails have reddish tails. Texas Spotted Whiptails are found from southern Oklahoma to north eastern Mexico and west to the southeastern corner of New Mexico. Their habitat consists of grasslands, shrublands, dry creek beds and hillsides. Diets include insects and other arthropods. They are often seen around campsites, usually actively searching and digging for invertebrates. Whiptails are the classic examples of widely foraging lizards. Unlike sit and wait predators, widely foraging predatory lizards tend to have long steam lined bodies and longer tails (Pianka 1986). Lizards in the family teiidae (whiptails & tegus) and scincidae (skinks) have this type of body shape. Some whiptail lizards species only consists of females, they reproduce by parthenogenesis. The females lay unfertilized eggs that hatch into clones of themselves. The asexual whiptail species comes from hybridization between sexual species of whiptails. About 30% of all whiptails are parthenogenetic. The Texas Spotted Whiptail is not parthenogenetic, they reproduce by sexual reproduction. |
