The leopard gecko (Eublepharis macularius) is a popular, ground-dwelling lizard known for its docile nature and ease of care, making it a common beginner's reptile pet. Native to the arid, rocky regions of Afghanistan, Pakistan, and India, these geckos are nocturnal and can live for 10-20 years in captivity with proper husbandry. They are insectivores and require a specific temperature gradient and humidity range to thrive.
