Armadillo lizard

The body length of armadillo lizards is about 75-90mm as adults, with the largest reaching 105mm. The typical characteristic of the armadillo lizard is that it has obvious scales arranged in a band-like manner on its body. The body color is dark yellow. When it is injured, it will bend its head and tail into a ball to protect its soft abdomen.
The number of scales located on the body is 15. Males have about 26-32 femoral holes. Once you are hurt, you quickly get into the rock cracks to take shelter. With appendages 2 for. The body is small, with external ear holes, and the full membrane is located on the surface or deeply sunk. The eye has moving eyelids and nictitating membrane (3rd eyelid). The tongue is well developed, flat and muscular. The two halves of the mandible are firmly connected by sutures, and the mouth's expansion is limited. Each tail vertebra is divided into two halves, front and rear. The tail can be broken off by strong muscle contraction. The broken tail beats vigorously and vigorously to distract the enemy, but the lizard takes the opportunity to escape; it can then be revived. A new tail, but shorter than the original tail and lighter in color, with only cartilage rods and no tail vertebrae.
The difference in the internal structure of lizards and snakes is: lizards have forelimbs and sternum, while snakes have none. Snakes have bifurcated ribs at the end 1 to 2, but lizards never have bifurcated ribs. The kidneys of snakes are closer to the front of the body, and the right kidney is further forward than the left kidney. The kidneys of lizards extend backward, even beyond the cloacal cavity, and are arranged symmetrically on both sides.
