The Aridinians were a race of mammalian humanoids native to the Inner Rim planet Aridinia. They had elongated skulls penetrated by a large hole. They lacked ears and noses, but their skulls were covered in fine hairs which were very sensitive to sound waves, and their skin underlaid by glands that allowed them to smell. They had sharp, bony ridges around their mouths instead of lips. The Aridinians had distendable throat pouches, elongating them to emit a loud call which helped in communication over long distances. Their folk music had, by 1 ABY, become famous across the galaxy for its ability to make Human ears bleed after a few notes.
