Guinan Toad-headed Lizard is an ovoviviparous lizard.
Guinan Toad-headed Lizard lives in caves, usually on the slopes of hardened gravel, sand dunes and earth ridges, and some are under gravel. The cross-section of the cave entrance and tunnel is half-moon-shaped, and the size varies with the size of the individual sand lizard, with a width of 1-5 cm and a height of 0.8-1.8 cm; the cave entrance is mostly facing south or southeast, and a few have no fixed direction. The tunnels are mostly unbranched and rarely bend, slanting underground, and the length and depth are proportional to the size of the sand lizard individual, 20-110 cm long, and the vertical distance from the deepest cave bottom to the ground is 80 cm.
Specimens obtained at an altitude of more than 3,000 meters were dissected to confirm that Guinan sand lizards are ovoviviparous. From late May to June, there are eggs of different development and degree in the oviducts of different female lizards, and the number of eggs or embryos is generally 2-4, and a few are 1; in late July, there are eggs of different development and degree in the oviducts of a few female lizards, and the number of eggs or embryos is generally 2-4 (the number of MIT is 1); in late July, a few female lizards begin to give birth to young lizards, and a large number of young lizards of the year can be seen after mid-August, and individual female lizards waiting to give birth can still be found in early September.
