The California spiny-tailed iguana is a large lizard with a strong tail covered in sharp spines. It lives in arid areas of the Baja California peninsula in Mexico.
The California spiny-tailed iguana differs from related species with particularly large and sharp spines on its tail. It is important for nature because it disperses plant seeds and serves as food for some predators.
Immature form that undergoes metamorphosis before adulthood.
