Seven-lined Whiptail
Seven-lined Racerunner
The Seven-lined Whiptail or Racerunner, also called Deppe's Whiptail, is native to Central America from Mexico through to Costa Rica. Photos were taken by Alexandra Makhnina. It can have pale green areas and has 7 or 8 narrow pale stripes on the back. Body length is some 3 inches (8cm) without the very long tail. Habitat is sandy and coastal grass dunes on the northern Pacific coast.

It is related to the similar-looking Six-lined racerunner (Aspidoscelis sexlineata) and to the Desert Grassland (New Mexico) Whiptail (Aspidoscelis uniparens) both of the southern United States and Mexico. Both can have similar blue tails. I mention the latter as interesting in that all are female and reproduce only via parthenogenesis.
