About This Species

The long-nose leopard lizard can often be found basking in full sun on rocks and other warm surfaces. When it is threatened, it "freezes" by running under cover and flattening itself into the ground. They are found in most of the United States' major deserts. They are easily identifiable by their leopard-like spots.
