The Green Crested lizard has a vibrant bluish green head with a oddly dark ring around each eye. They can turn their whole body brown when they feel threatened. They also have a very long tail especially for their body size. On an adult their tail is about 16 inches (40 cm) and their body is only about 4 inches (10 cm).
