Green Pricklenape

Acanthosaura is a genus of lizards commonly known as mountain horned dragons, or pricklenape agamas. They are so named because of a row of dorsal spines which run down the back of their neck. They are arboreal lizards that are found in Southeast Asia. They are medium-sized, ranging from about 7½ inches up to 15 inches in length, depending on species and individual. They tend to prefer higher elevation areas that are dense with vegetation.
