The Runner Lizard is a species of descendant of a prehistoric lizard of 55 million years ago that evolved to run on its hind limbs and first started out as eupakeria-like animals, but later became fully bidpedal and theropod-like. It resembles a long-extinct dinosaur, Eoraptor, but without feathers. Unlike most non-dinosaur reptiles, it is warm-blooded. It feeds on eggs, insects, fish, small lizards, small birds, carrion, and small mammals. It is a small reptile, with different species ranging from about 1 feet long and 10 pounds to about 3 feet long and 30 pounds. There are about 4,250 species in this group of reptiles and all of them are indigenous only to Asia and Africa, but about 16 species were introduced to North America, South America, Europe, and Australia by humans and all 16 species adapted to their new environment (including human settlements) and are thriving. Many native Asian runner lizards are also adapting into new environments, including human settlements. Many species of runner lizards can survive in cities, towns, urban, and suburban areas.
