The ear is the sense organ that detects sound.

The vertebrate ear shows a common biology from fish to humans, with variations in structure according to order and species.

It not only acts as a receiver for sound, but plays a major role in the sense of balance and body position.

The word "ear" may be used correctly to describe the whole vertebrate ear, or just the visible portion.
