WHAT USE IS A HOLE IN THE HEAD OF A LIZARD ?

If you're a lizard, a hole in the head is very useful
because it's probably an ear.

most lizards have an ear on each side of their head.it's just an open hole leading down to the eardrum inside.

reptiles' ears don't stick out from their head like ours do,
and snakes' ears are hidden inside
