Threats to natives: None known, but it presumably will prey on smaller lizards. The urbanized area where it occurs probably does not support populations of our native teiid, the six-lined racerunner (Cnemidophorus sexlineatus).

Species Account: The giant whiptail is a large (males up to 33 cm) teiid lizard from northern South America. At least 1 thriving population was established in Miami by 1995 (Bartlett 1995), but its present status is unclear because of continuing construction (Bartlett and Bartlett 1999). This population probably resulted from the deliberate release of animals, although no known reptile dealers are located nearby (Bartlett 1995). Another population was discovered on the edge of Everglades National Park near Chekika in 2004 (K. M. Enge, FFWCC, Quincy, personal observation). Habitat includes canal banks, nurseries, road sides, and office complexes. The back is golden brown and shades into tan or deeper brown on the sides. The body and base of the tail are liberally flecked with bright yellow spots, and the lower sides are black with white or turquoise flecks. The head and distal portion of the tail are russet colored. This alert, active lizard frequents open fields, canal banks, edges of grassy parking lots, and road shoulders (Bartlett and Bartlett 1999).

Habitats: Barren land, Low density suburban development, areas peripheral to core urban areas, and small towns, Agricultural habitat, Recently disturbed, early successional community
