Lizards are reptiles belonging to the family Varanidae in the order Scorpaeniformes. Lizards are distributed on all land except for Antarctica and a few Arctic regions. Lizards have a relatively fixed living environment, with only a few living in high mountains or water. There are approximately 5461 species of lizards in the world, which are one of the most charming reptiles due to their diverse body color, appearance, and obedience. Many species are kept as pets. Modern genetic research has shown that lizards and snakes are a group, with snakes evolving from lizards. Lizards have a snake like body, thin scales, are four or five inches long, and have four limbs, hence they are also known as "four legged snakes".

The giant ring tailed lizard is a diurnal burrowing lizard. They are usually distributed in dry rocky areas, inhabiting rock crevices or carved caves, and their habits and environment are very similar to some rock dwelling king lizards. Animals such as crickets, bread worms, leafy vegetables, fruits, and flowers will all be accepted. The environmental arrangement for raising giant ring tailed lizards can be based on reptile sand and stacked rocks, which are sufficient. They also require a large amount of sunlight, so high-quality UVB light is an indispensable equipment. In summer, they need 12-14 hours of sunlight per day.
