The leopard gecko or common leopard gecko (Eublepharis macularius) is a ground-dwelling lizard native to the rocky dry grassland and desert regions of Afghanistan, Iran, Pakistan, India, and Nepal. The leopard gecko has become a popular pet, and due to extensive captive breeding it is sometimes referred to as the first domesticated species of lizard. Leopard geckos are small lizards that derive their name from their spotted coloration. Hatchlings are on average 7 to 10 cm (2.8 to 3.9 in) in length and weigh about 2 to 5 grams. Adult females are about 18 to 20 cm (7.1 to 7.9 in) in length and weigh about 50 to 70 grams, while adult male geckos are about 20 to 28 cm (7.9 to 11.0 in) in length and weigh about 60 to 80 grams. Unlike many other geckos, but like other Eublepharids, their toes do not have adhesive lamellae, so they cannot climb smooth vertical walls. (Source: Wikipedia.org, CC BY-SA)
