Can earless lizards hear?

This means, of course, that even without a surface or subsurface-mounted tympanic membrane, many “earless” reptiles can indeed “hear”, though to varying degrees. The tympanic membrane is absent in many fossorial (burrowing) and semi-fossorial lizards, such as the legless Anniella, as well as in other reptiles, such.
