lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less
