During at which time the males tend to get competitive with each other. It lets other lizards know this is their territory. Keeled earless lizards regulate their body temperature by being diurnal. They come out during the day and bask in the sun or lay on the warm sand to raise their temperature. When night comes, and it gets colder, they burrow into the sand to get warm.
Lizards have special tails that can regenerate.
This special and unique adaption gives them some protection from preditors. If a preditor grabs their tail, unlike a mouse, the lizard would not be unable to get away, their tail would just break off. After the tail is broke off by the preditor it keeps the preditors' attention by wiggling, which gives the lizard time to escape. When attacked by a preditor Keeled earless lizards scurry away and burrow into the sand, by using his head to wiggle his way underneath. After the attack the tail will eventually grow back.
